[mythtv-users] ext3 to xfs conversion worth it
I finally got around to converting my root partition on my combination frontend/backend mythtv box from ext3 to xfs running on FC3. Deletions of recordings were taking forever with ext3, and they are much faster with xfs, just about instantaneous. In general all disk access seems to be faster, but that may be my imagination.

RE: [mythtv-users] Re: atrpms-package-config vsmedley-package-config(was: Fresh FC1 and Myth 0.16 installobservations/questions)
I feel like I have gone through all of the necessary trouble shooting steps to resolve install problems for mythtv, but I am really not having any luck at all. I even ran the script to rebuild the database as listed in Jarod's FC3 install guide. It was not this hard last time I tried to install myth on FC1. Again, can anyone please help me? Thanks, George FC1 is no longer supported so you are going to run into a few issues with modules being old. Try installing each module by itself. Install mythtv first, leaving mythdvd for last. A better bet would be to install fc2 and start again with that howto. It can be done with fc1 but you may have to compile your own.

I feel as though I have not read about any of these issues on the documentation pages, which may be my opportunity to contribute in due course All you need is a splitter and 2 short pieces of tv coax.

As it turns out, they're also the only possibly likely ways to watch HD for those who can't put up antennae for HD. (ie - I live in an apartment!) The good news is that for someone with the hardware and some C++ experience, it should be simple to add this capability to MythTV. You just need code to change channels, grab data from the FireWire port, and spew it into the ringbuffer. You also have to watch the stream so you can mark keyframes into the database. hdtvrecorder is good example code, though it does more processing. It's possible the stream may need to be munged in some way -- you can test this now by doing a capture into a file, then do 'mythtv filename'. If it plays properly, the decoder is capable of playing the raw files, and you're good to go. -Doug signature.asc Description: OpenPGP digital signature ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Right now there are no consumer level encoders that can encode an analog HD signal. The people here are correct that capturing a digital stream would be the ideal solution, with no reencoding the quality would be much better. The proplem with this is that if all the cable companys encrypt their content then capturing digitally might not be possible. Either that or we could find some way to capture the encrypted stream and get a decoder to play back that encrypted stream, but that would suck for osd's and other such things. -- I probably still have a few gmail invites.

[mythtv-users] Guide data problems
Hi everybody, I've got a rather annoying problem with the guide data. I live in Canada, and use datadirect to download the data. Here is my understanding of how the guide data works: After the database is initially filled, mythfilldatabase will run everyday and do the following: Download data for days that have never been downloaded before (which tends to be 13 days away. Refresh data for today and tomorrow. The problem is that the 13-day away data is often incomplete, and is not refreshed until the day before. If I sit down to plan my programming once a week, then I will often miss stuff, or have conflicts that I don't know about. Would it be possible to refresh the data for day d somewhere between d-13 and d -1, say on d-8? I suppose that this would increase the load on the datadirect servers somewhat.

With the old 4363 driver it used the /dev/nvidia method, which no longer works with later drivers. I'm not saying this code is buggy, but it may be exposing some other problem in your system. In the Nvidia/Linux forum, lots of folks have reported problems (lock-ups, X using 90% of CPU, etc) with the Nvidia linux drivers, especially when OpenGL is used. Also, have you tried testing video playback with other programs? Try the following: mplayer -vo xv file mplayer -vo gl file mplayer -vo gl2 file Do any of those cause problems? If so, suspect your video card or driver. You might also want to physically inspect your card. I have a LeadTek GF4 MX 420, and recently my display starting locking up with I start X. After much Googling, I took a look at the card itself and discovered that the chip fan had stopped working that the capacitors were bulging. I'm in the process of getting the card RMA'd. -JAC ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] mini-pci TV tuner cards
Hi Everyone, Next fun hardware question! Which mini-PCI form factor TV tuner cards have people had success running MythTV PVRs with? VIA's upcoming EPIA N board looks like an ideal compromise between going completely embedded-PC for a dedicated mythbackend machine, not to mention the fact that it uses the CN400 which does both MPEG-2 and MPEG-4 hardware decoding. At 12cmx12cm (just under 4.75x4.75) it would even fit in a 5.25 drive bay slot. See http://www.viaembedded.com/product/epia_N_spec.jsp?motherboardId=221 A few promising boards appear to be: http://www.provideo.com.tw/PV970.htm http://www.aver.com/oem/#notebooks http://www.yuan.com.tw/en/products/vdo_mpc622.html http://www.lifeview.com.tw/html/products/mini_pci/flytv_platinum_mini.htm Worst case, there are mini-pci to pci adapter boards: http://www.interfacemasters.com/products/pci_tools/mini_pci_to_pci/ ...but that kind of defeats the purpose. Follow-up question would be who sells your mini-pci card of choice, either here in Canada or at least in the US?

[mythtv-users] OpenGL with EPIA MII 12000
Hi all Since quite some time I'm trying to set up OpenGL so that I can use Goom in MythMusic and the blend effect in MythGallery with reasonable speed on my EPIA MII. Although everything is working it is so slow that it is of almost no use (although Goom works more or less ok if I use a factor 2 for visual scaling). What I'm wondering is if anybody has a setup fast enough to use the OpenGL blend effect in MythGallery or Goom without a scaling factor using an Epia MII 12000. My exact setup is the following: EPIA MII 12000 Debian unstable x.org 6.8.1 (installed over xfree86 deb-packages) Unichrome via driver (r28) / resolution 1024x768x16 DRM 2.3 I also tried the Unichrome 3D driver (binary release from SF).

Some applications when compiled for the ath-64 are faster. Some are _slower_ and you prefer to do them in 32 bit mode, though I don't think many are a lot slower. Of course, many of your RPMs will be in 32 bit mode for a while.I would suspect an mpeg decoder written with 64 bits in mind might do well, but I don't know if anybody has done that. However, no question, the P4-3ghz is way faster than the Athlon-3000 (not Ath64) at mpeg decoding.30% idle or less on Ath-3000. 60% idle on P4-3ghz. This is because the P4-3ghz is at 3ghz, while the Athlon-3000 is at 2.2ghz.

[mythtv-users] Interlacing with Scan Converter
Hi everybody I've got a little question as I try to tweak tv out quality on my box. I've got a low powered frontend (celeron 433) at my TV and I'm using a TVAtor Pro to feed signal to the TV. The video card is a TNT2 PCI. What is the best way to deal with interlacing using this setup. The original recorded signal recorded by the PVR250 (Freestyle) is obviously interlaced, and the signal sent from the TVator to the TV is also interlaced, but somewhere in between it goes funny. I'm pretty sure that the TVator expects a non interlaced 640x480 signal, and applies some filters to interlace it. So should I deintelace my video on playback? Will this be much of a performance hit? Would I have better results if I shelled out for a video card with TV out? Mark ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Though I don't think it's as much of a must-have as a PVR (which is odd because it costs a lot more). It varies on the type of show. Watching sitcoms in hi-def is nice. Dramas are also nice. Shows with cinematography like nature shows and travel shows are a major difference. Sports can be a whole new experience especially if the camerwork is done assuming HDTV. For me the big difference would be end-to-end digital content (i.e., no issues with analog signal quality, luminance/chroma issues with TV tuner chips, faded analog TV-out... just MPEG source content and DVI-out, even at crappy ol' NTSC resolution would be a big step up for me. After that, HD content is just the icing on the cake :-) -JAC ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

You can't capture HD over composite or S-Video, and a component video capture card would cost $USD 1000. So, *theoretically*, yes, an HD component video capture solution would get around the encryption issue, in the same way that composite/svideo capture currently gets around the encryption issue for SD (NTSC) digital cable content. However, an analog HD capture solution would require that your PC (or capture card) re-encode the raw analog video frames into a digital form, which would require some serious horsepower. Think about it: it takes a 2-3 GHz P4 just to *decode* HD content for playback; to *encode* it in real time would take quite a bit more than that. A hardware encoder card that would handle HD content would like be several thousand dollars. It's just not likely to be a viable or cost-effective solution any time soon. -JAC ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] AMD Athlon 64 CPUs and MythTV Compiling
I would go with the Athlon 64, the whole clock speed thing doesn't really matter as much anymore. In many cases a 2GHz Athlon 64 will outperform a 3GHz Intel. The Athlon 64 has a built in memory controller, lots of cache, and most if not more SSE and MMX type extensions. You would also have the ability to switch things to 64bit as they become available. All of the core Operating system and most applications are already ported and I would expect them to get much faster once people start optimizing for Athlon 64. And it does cost less.

Re: [mythtv-users] What happens when my cable company switches to digital?
I am using digital cable in the US. I only have one tuner card, I'm not sure how it would work with two. You would definitely need to STBs, but that is only part of the problem. You also need to control the channel on the STB. I use a serial connection to control mine, but depending on what model STB you get, and what the cable company decides, the serial port may not exist or could be disabled. If that is the case, you need to control it with an IR blaster. That should work fine for 1 tuner, but I don't know if there is a way in myth, to say use one IR blaster or serial port to control STB1 and a different one to control STB2.

Nice, in the sense that any time a card puts two functions on it that you want it's nice, but these are otherwise pretty unrelated functions. What they share is the RF tuner. The MPEG2 encoder would be only for the NTSC. The reason you would not want this is that if you get ATSC, you are only likely to want NTSC from cable/satellite, in which case you would not be using the tuner anyway. The ATSC tuning process doesn't really involve the traditional A to D used in a capture card. So what would be nice would be a card which is a combo of the pchdtv and a wintv-150. Though another argument is that those who are not splitting their frontend and backend will only put an HD card in a machine that can display HD, ie. a fast one. In that case, software encoding of raw capture isn't that much of a burden on the machine -- though capturing NTSC and encoding it and playing HDTV at the same time might be a burden. ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] What happens when my cable company switches to digital?
It is most definitely possible to support any reasonable number of STB's from a single myth box. You just need to create a separate instance of lircd for each STB you need to control. That can get a bit complicated, but if you google and search the list archives I'm sure you can turn up some info on running multiple lircd's. The thing that is usually most problematic is that, most likely, all your STB's will use the same IR codes so you need to make sure that each IR blaster/STB combo is isolated from the others. Otherwise you will probably end up with recordings from incorrect channels because both STB's will change channel each time any IR blaster sends a signal.

If that is the case, you need to control it with an IR blaster. That should work fine for 1 tuner, but I don't know if there is a way in myth, to say use one IR blaster or serial port to control STB1 and a different one to control STB2.

Re: [mythtv-users] AMD Athlon 64 CPUs and MythTV Compiling
Sorry, but as I pretty clearly said,the whole clock speed thing _does_ matter a bunch on this very specific application -- mpeg encode and decode. Other people have extensively benchmarked mpeg encode, and Pentiums win hands down. My own tests, described below, show the same thing for decode though I have not seen official benchmarks. For just about everything else, AMD is a better choice -- often faster, cheaper and lower-heat. But not for this one. For this one Intel wins, and the reasons are a combination of the fact that on some applications a faster clock really makes the difference, and some supposition that the long pipeline does matter on this particular app, though I have not seen that documented fully. But the CPU idle times are quite clear, I have two identical systems, one with Athlon-3000, one with P4-3ghz (512k cache), and the CPU used by the P4 is much less.

In many cases a 2GHz Athlon 64 will outperform a 3GHz Intel. The Athlon 64 has a built in memory controller, lots of cache, and most if not more SSE and MMX type extensions. You would also have the ability to switch things to 64bit as they become available. All of the core Operating system and most applications are already ported and I would expect them to get much faster once people start optimizing for Athlon 64. And it does cost less. However, no question, the P4-3ghz is way faster than the Athlon-3000 (not Ath64) at mpeg decoding.30% idle or less on Ath-3000. 60% idle on P4-3ghz. This is because the P4-3ghz is at 3ghz, while the Athlon-3000 is at 2.2ghz.

[mythtv-users] Plextor Mpeg4 Hardware Encoding N00b Requesting Advice
Hello to all, Does the hardware from plextor run under Myth? http://plextor.com/english/products/TV402U.htm It says it has hardware encoding for mpeg4, and it has a firewire port. If it has firewire, is it merely telling the device to record, and it spits it out as a stream through the FW port? Kinda like an on/off switch... Prolly more coding involved, but I would figure something like that would be a little easier to code than the 150. Am I wrong? I haven't looked. Again, I'm TEH N003. :P I haven't subscribed long enough to return any results for a search through my local e-mail. The list archive doesn't have a search function, so sorry if this is a repeated question. As for the advice... I am planning to build a system, and I was originally looking at one 350 and a 250 with a 6800 Ultra. Heard that the VPU was broken on the 6800, but I doubted whether there would be a linux driver for it even if the VPU worked. I'm ultimately interested in being able to play 1080i/p content on the machine, so the throughput of the videocard was a deciding factor. Will the 350/250 be able to decode this kind of HD content? Aside from 1080i content, I would -like- to use this machine to save shows to disk, but I continually see 1GB/hr. What is the quality of the recordings? I have seen files that are typically 350megs for one hour. I'm guessing they are transcoded down to a lower res. I would also be interested in archiving seasons onto DVD, but 4 shows per DVD versus 12 sucks. True, DVDs are relatively inexpensive nowadays. However, if I were record 1080i content, would I be able to accomplish this using an FX55 with one of the tuner cards? Would I have to use a simple frame grabber card and then encode after the data has been saved onto the HDD? (I figure if there is no encoding before it hits the HDD, it would eat disk space like nothing else. If so, what kind of space consumption am I looking at?) What would the requirements be for recording 1080i content? Am I only limited to commercial hardware that cost a lot? I wouldn't be saving a lot of 1080i content--I would only be interested in saving particular shows from ATSC or HD-DTV for later editing to create some montage of clips for a demo file. Also, I was planning to have a SCSI drive with the system installed on that with a SCSI DVD ROM, so as to free up as much CPU cycles as possible. (I never really liked the fact that IDE/ATAPI/SATA takes up your main CPU just to read and write data.) ...Anyway, is there a way to configure Myth to temporarily store the data on the SCSI while recording and also when you want to play? I.E. it records your shows to the scsi drive, and during an idle period moves it over to the secondary storage device (external FireWire, in my case). For playing, you would select what show you were going to view and it would transfer over the file to the scsi drive? I was thinking about pre-viewing transfer for 1080p content. Course, after it's moved it to the secondary drive, it keeps track of it for later viewing. Maybe this could be done with symlinks. I haven't bought the entire system yet, so I haven't been able to test Myth. I'm not sure of its capabilities. Just trying to figure things about beforehand. Hrm. I was just thinking... What if Myth could store data (when a setting is checked) on a network drive in chunks of 1gig. Then, a script running on a Dual G5 2G would encode the files into a mpeg4 video file and delete the read 1gig chunks as it goes? I dunno. Just thinking aloud.

RE: [mythtv-users] question on movies
Welcome to Myth, Mark. What you're referring to is a plugin/feature called MythVideo. Video files are stored in a designated location on the backend/frontend (you'll learn that later...check this list). This is /var/mythvideo by default, I think, but you can change it in the configuration menus. Mine is at /video/mythvideo. Mythvideo uses mplayer as its external video player, so it will play back the formats it supports. The video manager GUI for MythVideo is rather nice, in that it displays the movie poster and Imdb info when avail (if you setup your video manager properly).

I assume this would work with all DVB-T cards (like my avermedias). Yes. If this is the case, what are those OSS MythFilters I downloaded for??? It's for playing nuv files. Once again, I beg the devs to see if it's in their hearts to add support to the code for actually using the .mpg file extension for recordings that really are mpeg files and not nuv files. It might make some parts of the code a tiny bit more complex, but having mpeg files with nuv suffixes is probably the SINGLE most confusing issue about mythtv that we have to deal with in #mythtv-users. Some people just don't seem to understand that nuv can refer to both mpeg files and nupplevideo files -- and in reality they shouldn't have to. .nuv files should NOT be mpeg files, they should be nupplevideo files. I know this was done to keep things easier in the code, but it's a support nightmare.

But you do get the advantage of an extra eight registers, which makes a huge difference to most code as the x86 architechure is very short on registers which gives optimisers a very hard time. I've seen programs which don't do much 64 bit maths go 50% faster just by recompiling for x64-64. So, for those running Athlon-64s, what sort of timings are you getting with the myth internal player compiled for 64 bit and for 32 bit, compared to the regular athlon xp and the P4? In the end, the best way to tell is just to try it out. Some code will make happy use of extra registers or wider registers. Some doesn't. Some even gets slower, because it keeps reading and writing 64 bits when all it needs is 16 or 32. Plus programs get bigger, and bigger program equals slower depending on cache performance. Of course, with the right coding, it seems that a 64 bit mpeg decoder written for ia64 could do well, but I am not sure we have one around. Of course, if it were not for the xvmc problems in myth, the simplest answer would be to use xvmc and get a nice, cool, slower chip like a Sempron 2000 which is dirt cheap -- and I think could handle things with xvmc doing the work. (Of course it would be much slower at transcodes and commercial flags.) Right now commercial flag is pretty slow if set at low CPU. On the Athlon 3000 it seems to run at about realtime -- 3 hours to flag a 3 hour show. Presumably on the wishlist is the ability to start a commercial flag thread immediately upon starting recording, and almost as importantly, to make the results available as they are generated and confirmed, instead of waiting until its all done. If you have the CPU, you could then watch shows closer to airtime and have them flagged. I am actually surprised at how unreliable the flagging is for me, others have reported much better, some even have said they turn on automatic skip, which would be a nightmare for me.

I'd like the scheduler, at 9:01pm, to recognize that program 2 is only 1 minute into the show and start recording it when the tuner becomes available despite the 1 minute overlap resulting in 1 minute missing from the second show. I don't like setting the record late option on program 2 because it will *always* record late even when there is no conflict. In an earlier discussion on this it was stated that when there's an overlap like this it stops recording the 1st one automatically and starts recording the 2nd at the time the 2nd is due to start - even if the 1st one was supposed to run on. So, if that's correct it already does what you're proposing except that it doesn't wait for the tuner to become available. I think we need to get a firm statement on just what does happen in this circumstance. Of course the sure-fire solution is to get a 2nd tuner card! ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
[mythtv-users] lirc and FC3
It seems that almost everyone who has used FC3 with kernel 2.6.9 (or some deviant thereof) have had problems getting LIRC to work. I have tried to get mine working, unsuccessfully. I am following Jarod's guide, and have a PVR-250 using the IR receiver that comes with it. I have done the fix found here: http://bugzilla.atrpms.net/show_bug.cgi?id=317 but I have not been able to get it to work. It worked after first installing it, but died after the reboot (just like many other people have had problems with). I have played with some of the suggestions posted on the listserv as far as reinstalling LIRC, doing a "/sbin/depmod -a" and then "/sbin/modprobe lirc_i2c", and then "/sbin/service lircd restart" (I've done those 3 things in various orders) but that doesn't get it to work either. Basically, when I run "/usr/bin/irw"it does nothing. If I do it again, Can someone please post a workaround as far as how they got it working? I'm still a n00b at this, so if you could be a bit descriptive to help with my lack of knowledge with linux, that'd be great. Thanks. -Andy FC3 Kernel 2.6.9 (the one jarod's guide says to install here: http://wilsonet.com/mythtv/fcmyth.php#kernel) PVR-250 w/ grey remote and the packaged IR receiver ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Video Cards
I am building my new HTPC with MythTV, and want to know what impact video cards have on the system. This system will not have a monitor permantanly attached, it will be viewed on teh TV only (I will have the monitor for setup only). Because of this, does the WinTV-250 or other part of the MythTV system use the video card for processing? Will any card do, or do I need a good video card? Do you mean video card or TV Capture card? Both are important. Everyone seems to like the Hauppauge cards as they have hardware decoders so don't use the system CPU for encoding tv capture. That's important if you don't have a fast CPU. I don't think the 250s have a TV-Out so you'd also need a video card with TV-Out. Cards with nVidia chips are generally good and lots of people use them so there's good support here for them. ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Enlighten me about 1080 interlace
I thought I understood this interlace stuff but Myth is challenging my concept of interlace vs. non-interlace video. I have a TV capable of displaying 1920x1080 interlaced. It's a CRT based RPTV from Pioneer, if you care. I have watched terrestrial broadcasts on HDTV and it looks breathtaking. The image consists of two alternating 540-line frames, each 1/60 second, displayed at even and odd scan lines for 1080 unique lines of information. Now I get my Myth box running and it looks very, very good. But not quite as good as my TV with a direct OTA receiver. Why not? I've set everything up as carefully as possible. I'm on stock 0.16 Myth, I have an Intel 3GHz processor running an nVidia 5500 card with Xv. The modeline is correct and the card is doing interlaced out, as evidenced by the flickering on 1-pixel lines with an xterm on screen. I'm no expert on this at all, but I had always assumed the picture will never be as good on MythTV as OTA direct to your TV as the video has to be encoded and decoded. Inevitable some of the original picture quality will be lost in that process, I would have thought. If it's _almost_ as good perhaps that's all you can hope for. ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] New here, feature suggestion
How about an alarm feature, you select a programme and set an alarm against it so when that programme starts if you're watching another channel it gives you a warning on screen. I like it. Alot like how my digital cable box works. Doesn't seem like to would be too hard to implement either. Add a option to the record options dialog which says 'Remind me' and when it comes to the time it pops up the OSD to warn you. You should add it to http://www.mythtv.info/moin.cgi/UserWishList to make sure it doesnt get lost in the archives. -- Jason Gabriele [EMAIL PROTECTED] ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Re: [mythtv-users] problem with mysql
You need to either update the host entry in the mysql.user table or grant the same user rights from your new ip address. Login as root mysql user: SQL grant all on mythconverg.* to 'mythtv'@'%' identifed by 'mythtv' flush privileges; /SQL substitute your IP address for '%' if you want more security. Or SQL connect mysql; update user set Host='%' where User='mythtv'; flush privileges; /SQL substitute your IP address for '%' if you want more security. '%' means any host. It's not recommended but it is very convenient if you're network is firewalled behind a NAT gateway and you have multiple frontend boxen.

No. In theory there is no reason why Myth's decoder would not be as good (or better) than the one in the TV. If you have DVI, the results should be identical. In practice, I am not sure myth's decoder is as good (I see more mpegging artifacts). And your modeline may never be the exact perfect one the TV has. Inside, the TV is just writing directly into its own frame buffer for the DLP.In theory, you could get your DVI stream to also just be fed into that frame buffer, if you did it exactly right. I'm surprised the TV doesn't figure this out for you with DVI, saying, Hmmm, here comes 1920 pixels, why don't I do with that just what I would do with stuff I decompressed myself. Perhaps some TVs do. What would give you identical results would be streaming mpeg out firewire, or, if an RF modulator was available, streaming out ATSC or QAM to a TV ready to receive that. I think it would be cool if the pcHDTV card came with an ATSC RF modulator on it as well as a demodulator. Like the very first VCRs, sending out their signal on channel 3. But this time doing _better_ than component video. Though you would have to write an mpeg streamer X driver, no small feat. ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Apparently the windows software is lame. Also it's not firewire, it's USB2, a cyprus semi chip. If we could only get specs, I'm betting this thing would make an excellent input for Myth, especially since you could hook more than one much more easily than consuming PCI slots. A review of the Windows version claimed that mp4 recording took 30% of his CPU, so they must be having the host computer do some work. But yes, in a way USB tuners meet my vision of the ideal PVR for the consumer, where they can add components as they need them just by plugging them in. Tuners, decoders, disks, etc. I prefer ethernet and IP to USB though, since if you want to just have a decoder you slap right on a TV (with IR receiver/blaster), you want to be able to put it on ethernet, as you may nto even have a computer in the room.

Re: [mythtv-users] Consecutive programs, dual tuners
On Tue, Dec 21, 2004 at 03:31:13PM +1100, Martin Brown wrote: Unfortunately, a second tuner card does _NOT_ necessarily solve this problem. You'd think it would but no. If the two programs are on the same channel, only the one tuner will be used, the end of the first program will be on the file for the second program. Sure, it's recorded ... until you edit or delete the second program to discover that you also lost the last bit of the first one. Bummer! I haven't seen it do this for two consecutive programs recorded from different channels. I'll try that one out. This sounds like a bug the more I think about it. Considered one of the great flaws of the Tivo as well. The right answer, when two programs overlap on the same channel, is to put the overlap minutes into _both_ programs. Ie. if I have a show from 8 to 9 with record 1 minute extra at end and a show from 9 to 10 with record 1 minute earlier at start on the same channel, it should just work. Two 61 minute recordings, sharing 2 minutes in common. If you want to get really fancy, you would in fact have them share the very disk space. To do that, Myth would need to convert to a system where single shows can be recorded in a set of files rather than a single file, and playback involves concatenating the files. This can be done if you pre-buffer stuff when heading for a transition so it never skips. This has a lot of uses, and in fact it makes a lot of sense that all recordings might be stored in smaller 15 minute or so chunks. It allows easy deleting of the front of a program, up to near the point where you've watched. It allows easy integration as described above. It allows easy deletion of the end of programs too, though you can also ask the filesystem to shrink a file there. It also is a path to the ultimate goal for live-tv watching, where live tv watching is actually identical to recording, but the recording is done in chunks so the old chunks can be removed to save space once watched. Yeah, it's always easier to talk than to write code! ___ mythtv-users mailing list [EMAIL PROTECTED] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
