My goal is to have the two PVR-250s record analog cable (already working), and the PVR-150 record OTA broadcast signals via my rooftop antenna since the reception of local channels stinks on our analog cable. I set up a new video source called antenna and configured a new local broadcast channel listing for my area at zap2it. However, it's not clear to me how this will get handled in the EPG. For example, channel 7 on analog cable is Discovery, while channel 7 on broadcast is PBS. After running mythfilldatabase these both appear in the EPG, but where channels are the same (i.e., channel 9 is the same station on both cable and OTA), there is only one entry in the EPG. What you need to do is go into the Channel Editor (either in mythtv-setup or mythweb) and change the channel number. In my case I have channel 7 (pvr250 connected to directv), channel 7-1 (wintv-go OTA NTSC) and 7HD (pchdtv 3K). Instead of creating additional channel 7s, couldn't you just leave the single channel 7, since they are the same source, and just increase the priority of the PVR-150? I would assume this would use the 150 first for channels that are available on it, and still use the 250s if there was a conflict. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I've tried following the directions on Jarod Wilsons site to get FC3 to automatically log in as mythtv and run mythfrontend but that's where I'm having trouble.

Has anybody gotten this successfully working on FC3 with KDE? If you don't really want to run KDE (if your only using your frontend for Myth, you don't need it), there is a solution posted a couple of places that has worked very well for me. You edit your /etc/inittab file to spawn startx. It even restarts it when X exits. I use the following line: 2:345:respawn:/usr/bin/openvt -fwc 2 -- /bin/su - mythtv -c /usr/X11R6/bin/startx The options to openvt are a little different than what were posted, I had to mess around with them since the options seem to have changed between openvt versions. This replaces the old line in inittab for tty2. It basically opens a virtual terminal on tty2, and as the mythtv user, calls startx. My mythtv user has a .xinitrc file that starts a window manager in the background, and then starts mythfrontend. When myth exits (or dies), X stops, the init process notices, and starts it up again. If I don't want mythfrontend to run, I can switch to runlevel 2. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Other solutions would be to find a way to adjust the threshold percentage at which a day's schedule is considered complete, or to find a way to make a certain range of future dates mandatory updates (so that the percentage of filled time slots is not considered beyond day 10, for example, meaning that days 2, 11, 12, 13 and 14 are all downloaded every night). Those probably require hacking the sources. This is what I have had to recently do. mythfilldatabase was checking that there where at least 4 times as many programs starting after 6pm for a given source as there are channels. This is in programs/mythfilldatabase/filldata.cpp . After changing the code to require only twice as many programs starting after 10pm as there are channels, my problem was fixed. (My data was only missing for cable channels after 10pm). If you search for d 18 in that file, that is the sql line that gets the number of programs starting after 6pm (18:00), and about twelve lines down is a line that ends in chancnt * 4, that decides if there are enough programs for that source. I ran the query manually against filled schedules, and broken schedules, to come up with the timespan and multiplier that fixed my issue. I can't remember if someone already mentioned this, but the reason you always have two good days of data is that mythfilldatabase always refreshes the data for tomorrow, even if it is full, in case there had been scheduling changes. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

The likely explanation is that the channels with missing data have not provided zap2it (or the people they get it from) with the data. That makes sense. I get missing and even incorrect data for some channels, often the independent ones, if I look towards the end of the available range. For me, I just don't look that far into the future, and by the time those days get refreshed the info has been updated/corrected. The problem is that 90% of the channels are missing. It's pretty much divided by local affiliates have data, the common cable channels do not. Once mythfilldatabase gets *some* data for a day, it does not update it again until the day before, and most of the shows I record play between 8pm and midnight, so this doesn't give the scheduler too many options when there are conflicts, since it only has two days of data (today and tomorrow) to look at. I'll see if my '--maxday 10' trick helps. I guess I find it odd that if I'm not getting all of the 14th day of Comedy Central, no one else is seeing this either. It had been working, so I'm assuming it is not my configuration. Another possibility I suppose is the time that mythfilldatabase runs? I have it run between 2-3AM. I'm wondering if I pull it back before midnight, the furthest out day will not get borked. But that would just be the equivalent of pulling one fewer days.

So / , /dev , /var would be in the ram disk, and /usr and such would be mounted from the CF. An advantage to this would be that would would save RAM by not loading all of /usr into memory. You don't want to mount directories such as /var on the CF, CF can only handle a certain number or writes (10s of thousands?) before it fails, and the constant writing of logs and such can quickly wear out the flash. It's not relevant for /usr, since it would be mounted RO. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

I'm currently finishing off an XBOX front end and although it's not unattractive I'd like something attractive and quite. Thanks for all the great information and feedback. I'm using a Casetronic C-158-60W. It has a small fan, and my M10K has a small fan. It makes a very small amount of noise, but not noticeable at all over the pump in my aquarium. When I had the aquarium off today to clean it, I didn't hear the front end at all though. It comes with a riser card, but I'm not using it. I replaced the power switch/hdd+power led in the front of the case with a circuit board I made, replacing the hdd led with an IR receiver and support parts, plugging into the COM2 header on the motherboard. It didn't work so well with such a small hole (I hoped the little plastic through-lens would work both ways, but you had to aim straight at it), so I drilled it out to be the same size as the power button, and put a thin red sheet of plastic behind the hole. Had I not wanted to put an RF transmitter on the same LIRC port, I would have been much better off buying an IR receiver. In the end, I'm pretty happy with it, the box looks nice, and came with all the connectors and screws that it should have. My only complaint is that the blue power led in the front is *way* too bright. Had I thought about it, when I rebuilt the circuit board, I would have added a resistor to dim it. Instead, I just have a piece of paper in front of it inside the case to take it down a brightness notch. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

If you are using a newer version of the driver, it will also have 720x480Noscale, which I use, that has only a little overscan, and turns the scaler off.

Unpacking that file and looking in the Sony directory, I do not see any of your Sony remotes, but grepping them for RC5 only returns one match, so I would suspect Sony does not use RC5 protocol. Grepping in the jvc directory for RC5 returns no matches. I think Philips came up with RC5, there are many matches for it in the philips directory.

That's how mplayer and xine seem to work. For example, mplayer's fast forward command is: begin prog = mplayer button = Forward config = seek +10 end In other words, activate the 'seek' command with a '+10' parameter (go forward 10 seconds). In MythTV it's: begin prog = mythtv button = Forward config = end Where you have to then define '' somewhere else. I don't know why it was done the way it was in MythTV, maybe it's the easy way, but I'd love it if someone would change the MythTV lirc stuff to be more like mplayer, etc. Ben The problem I see with this in Myth is that there are many modes in Myth, where you may want the same remote key to perform a different function in different modes. This would be problematic if the function name was in the config line. Not that I have a better solution. What I would like is more fine grained keys. I have my remotes play key mapped to space, and I like that in menus it will select the menu item, but when video is paused, I would like it to unpause, and when video is playing, I would like it to display info like the I key does now. If the play button was mapped to a function name this wouldn't work. As it is now, I would just have to add more fine grained key mappings. This thought just came to me. Maybe there could be separate mappings to myth functions for keyboards and remotes. You could still map keys like now, but you could have lirc pass in the name of the buttons, and in Myth you could map full button names to functions. Dunno. Just rambling. What got me started on the Ctrl key thing in the first place was the note in the keybindings page of mythweb that explicitly suggests to use modifiers for jump points, to avoid overriding regular functions. Maybe I'll see if I can fix the Myth lirc code to handle Ctrl keys.

Unfortunately playback on the VIA based box is stuttering, thus it plays well for half a second or so, then stops for 1/3 second (video and sound), then plays for another half a second, stutters again ... I am using an M10K. I have had a series of video stuttering problems, which I have mostly worked through. The one you describe is the like first one that I had. In my case, I was still setting up, and experimenting, and had not yet set up the audio out yet. I had installed for ALSA, but my settings where still for /dev/dsp, which I got a warning about every time I started playing something. The video would pause just as you described, until I went in and changed my audio options to use ALSA, at which time both the audio worked, and that type of video stuttering stopped. Also, what type of tuner are you using? Another source of stuttering was the ivtv driver, which doesn't quite support VBI yet (sounds like it is getting very close, but definitely didn't when I was having the problem). When I ran the mythtv setup, and turned VBI to NONE for my ivtv cards, all but the slightest stuttering was gone. The only stuttering I have left happens for about 15 seconds every half hour or so. The CPU is normally 80% idle during playback, but during this time it is only 10% idle. It lasts for such a short time, and the the stuttering is so light, I haven't taken the time to really dig into the problem.

[mythtv-users] Occasional problem starting mplayer from MythVideo
I should probably post this over on an mplayer list, but since it is happening under Myth, I thought maybe someone here has seen this. mplayer (1.0pre6-3.3.5) usually works when MythVideo starts an mpeg2, but when it doesn't, it tries to display an untitled window. Once the window is placed it immediately dissapears, so I do not know what it says. If I place it with clicking the mouse, the window dissapears, and I can try and select the video again. If I add RandomPlacement to my .twmrc so I don't have to get up and hit the mouse, I am not asked to place the untitled window, but Myth appears to be hung without some of the video selection screen redrawn. When it is working, the Trying to re-lock decoder message is printed thousands of times, so when mplayer does not work the error would seem to be X11 error: BadDrawable (invalid Pixmap or Window parameter). Nothing odd appears in my Xorg.0.log. I would say calling mplayer works about 9 times out of 10. My player settings for mplayer are mplayer -fs -zoom -quiet -vo xvmc:deint-bob -vc ffmpeg212mc %s If someone knows how to get mplayer to fail without either requiring the untitled window be places, or locking up Myth, I'd be happy with that. If there is a way to get mplayer to not fail, that would be ideal. Any tips on getting the thousands of re-lock decoder errors from appearing in the logs would be appreciated as well.

Howard I would have thought the same thing, except that the live TV in the EPG is scaled and inserted into an OSD, and that uses the same 20% cpu for me. So I would assume that displaying an mpeg2 preview on an OSD would be no different. But looking at the code, I got lost, and realized that it would take me a lot of studying to get up to speed. So if I was doing something stupid causing it not to work, or if it can't work for some technical reason, I'd find some simpler thing to try and tweak first, that had a lower learning curve. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Re: [mythtv-users] Request info from working M10K frontend.
Thanks to everyone for the replies. I'm going to try installing knoppmyth, and upgrading it to .18, since that is what the backend is now, and I had the same problem with .17. Since Jon has it working, and his interrupts look the same as mine, I can stop going down that path. I did try a pci nic, and it had a different interrupt than the video, but that did not solve the problem. Bummer. I sat squinting at the -v all logs into the wee hours last night, and came up with this puzzling thought: I assume the capture card has to capture at the rate the video source is clocked at, and in my case, the audio is sampled at 48kHz. On the front end, the video is written in sync with vertical retrace, and I assume the audio is written in sync with the video according to timing info in the stream. My question is, what happens if the video source rate is slightly slower, or the because of my video modeline, the output is slightly faster, than the standard. Or forget the standard, what if the source is slightly slower than the sink. I know the standard sets the display rate, but no two clocks are identical. In the case of live tv, would the ringbuffer slowly be drained, causing the pauses when it runs out? Or is myth able to compensate somehow? How about the audio, what happens if the frontends clock is slightly faster than the backend, is myth able to adjust the audio output rate, or does the audio buffer drain, causing pauses? What I see in the logs is a REQUEST_BLOCK _RI immediately after every Read(). At first the time of the Read() after the request is very short, but then bumps up to a slightly larger number. At this point, the audio buffer is slowing falling behind, until it runs out and pauses. When it restarts, there is a brief period of fast responses from the backend, but it then falls back to the old rate, the audio buffer again falling behind. I'm going to try and graph the response times, the audio buffer size, and the pauses, and see if I still see that pattern, now that I've had some sleep.

[mythtv-users] Request info from working M10K frontend.
Howdy. ** Background I've posted a few times about stuttering video on my M10K setup using XvMC. Since I didn't have the problem without XvMC, just video tearing, I assumed XvMC was the culprit, and have been spending evenings trying different versions of DRM/XvMC/VIA. Well, today I went nuts (that's what this has been driving me to) and tried a few different tacks. First off, this is an EPIA M10K diskless frontend running .18. First, in case my hub had issues, I put the frontend and backend on a different 5 port hub. Made no difference. Second, I noticed that video and ethernet used the same interrupt. I used setpci to change the video one, and it would show that it was changed, but when I started X, it attached to the same old interrupt. No go there. Third, I thought maybe being diskless was causing problems. I took an old laptop drive, copied the otherwise working root image onto it, tweaked /etc/fstab and the root boot option, and fired it up. Booting from disk worked fine, but playing video still had stuttering. Next, I copied *one* nuv file from the backend to the drive in the frontend, stopped the front end, moved some directories around so myth would think that file was from the backend, and started it up. Worked *flawlessly*. Well, there was one pause immediately when starting up, and two in the last 8 seconds. I'm not at all worried about that. So I guess I can stop messing with video drivers. ** Questions Could someone with a working M10K using built in video and ethernet, with a separate backend, provide me with the following info?

I'm not able to get anything to use int 5, and you have eth0 there, which is what I would really like to try. I just tried turning on PNP and clearing the config in the BIOS, and trying ACPI. From the boot log, it looks like it will only route to interrupts 10, 11, and 15. Maybe I'll hop over the the viaarena forum, and see if they have any ideas. I notice you have yenta loaded, google tells me that's pcmcia related. Are you using an MII? Is your eth0 on pcmcia, or are you using built in? Also, you have ivtv loaded, not too many ethernet interrupts, and quite a few ide0 interrupts. Is your system just a frontend, or is it both frontend and backend? I ask because when the nuv files are local, I don't see the problem. I too am seeing some stuttering with 0.18 on the Epia. First it was due to DRM. Once I got that resolved, it would stutter when starting up. When I first included support for the Epia (Unichrome) in KnoppMyth, CPU usage was 50% when using the CD as a frontend, now it is 92%. Doing an install to hard drive uses the same amount. If I compile on the Epia or use my i686 debs, CPU usage is about 50%. Before, it was about 13%. So something is amiss, I just cannot put my hands on it... With XvMC and .18 on the frontend only Epia, I am seeing roughly 20% cpu usage, which makes this problem even stranger. About 3% cpu on hardware interrupts, 3% on software interrupts, and 0% wait. That's what's making me think network latency now, and checking out the shared video/ethernet interrupts situation. Now that I have a disk in there, and no longer need net boot, I'm going to try a nic in the pci, and see if I can get it on a different interrupt that way, just for giggles.

[mythtv-users] M10K XvMC video stuttering
Sorry to beat a seriously illin horse, and for the long post. I was having this problem with .17, and waiting to see if it went away in .18, because I hadnt been keeping up with patches. I know turning off XvMC solves problems for many people, and that XvMC support is improving. But I also thought that XvMC is working well for people with EPIA M10K setups. Im having a problem with stuttering video/sound on live tv playback. Playback from recorded content plays fine. With both XvMCs enabled (or just the VIA one), and deinterlace Bob (2x framerate), the picture looks great, but there are bursts of prebuffering pauses and WriteAudio: buffer underrun messages that go along with stuttering video. With both XvMCs disabled, no deinterlace, there are no pauses, no bad log messages, but there is video tearing. With both XvMCs disabled, and bob deinterlace, video is shown twice, split screen, with same picture squished on the top and the bottom, colors are funny (lots of purples and blues), and the whole screen flickers solid green. Its a little noticable. Ive just built a new backend with a different MB/CPU, so I dont think it is backend hardware related. Im using the following Debian testing X.org 6.8.2 Unichrome VIA driver from CVS, checked out 2005-03-15. freedesktop.org DRM driver from CVS checked out 2005-02-10. MythTV 0.17 (now .18) I tried more recent checkouts of the VIA driver and DRM, but still had the same problem, along with some new ones, so I rolled back. Other than the pause and underrun messages, there are no errors in the frontend log. The log does mention XV and VLD are being used: 2005-04-16 14:00:42.913 Using protocol version 15 2005-04-16 14:00:45.099 Opening audio device 'default'.

No swapping at all. top shows no IO waiting, plenty of idle CPU (60-70%). There is about 3% hi and 3% si in top, which I can't find a description for, I don't know if that is a problem. The stuttering is very bad when I first go to live TV, or when I change channels, but then smoothes out after a minute or two. It never goes completey away, it can come back in bursts, but isn't nearly as noticeable after a while. If I pause so I'm 15 seconds behind, it doesn't seem to help, but if I pause about 1 minute or more, it seems to rarely pause once I start again. I didnt think the 3D parts of OpenGL were used, but I figured if I could get a good glxgears value, it might indicate I had the drivers set up properly. Before doing this, glxgears was around 50fps, and after going through the motions, it is now around 530fps, so I think I have OpenGL set up properly. Playing prerecorded content works smoothly. Two smaller problems, they are not a big deal, but if there are any ideas it would be nice to cross them off the list. 1) When watching video, overscan hides the VBI dots at the top, but they are visible in the program guide, and the preview of recordings. I know the crop filter doesnt work with XvMC, but I gave it a try just in case XvMC wasnt used in either of those two modes. crop=1:0:0:0 had no effect. 2) When entering and exiting the program guide, the video jumps down and left slightly between the time the guide is selected, and actually appears. Not a huge deal, but it is pretty noticable, since this causes the VBI to be visible. Any suggestions?

I can't remember what package it was, but I've had trouble compiling things for my epia on my desktop machine. The issue was that I compile for epia with -march=c3, and the offending package built a utility for itself, and then failed running it since the desktop didn't have the c3 magic. I'm sure there's a better way around this, assuming the offending package supports cross compiling, but being the lazy person I am, I just build everything for my frontend on my frontend. Sort of computer assisted procrastination. Regarding giving up on epia, I don't have any of the DMA problems, or even FF/REW problems (although the machine is diskless, so I suppose there are fewer DMA contentions), but I have had more than my fair share of video problems. Part of the problem is possibly caused by a problem with my TV (some picture distortion), but also video stuttering problems with live tv, which seem to be XvMC related. I haven't applied all the patches to .17, but I think I read there are XvMC VLD changes in CVS I don't have that are related, so I'm crossing my fingers and waiting for .18. I'm not giving up on my M10K yet, but if I knew then what I know now, it's not the way I would have started. -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

Did u compile with opengl-vsync on? Once that disabled, playback is fine on my machine... Regards. Tj Sadly, no. Always looking for the easy fix. I turned on full logging on the backend and the frontend, but I'll need to do some homework before I can total sense of it. It does look like the audio buffer is constantly low, but until I look into what code is writing what messages, I won't be able to decode what is happening. Thinking about this, I came up with what would be a cool debugging tool. It would be slick if there were dummy sources/sinks, that could be plugged into myth, and could be used to stress test the various parts of the system. So there would be a module that acted like a frontend, and tried to stream data from the backend at a rate that was stepped up until the backend couldn't keep up, and then printed statistics. Or a simplified backend that was capable of sending a simple stream (something like gears) at a high rate and logged stats about the requests from the frontend. Maybe this functionality exists, dunno. I do know if I was smarter, I would write it. I don't know if my problem right now is a slow backend, frontend, or network. I assume it is not the network, I'm using 100Mbps with a switch, and I tried copying files over NFS from the backend to the frontends /dev/null (frontend is diskless, nowhere else to write it that wouldn't interfere with the network), and noted a fairly decent throughput. Still on my list of things to try is use OSS instead of ALSA. Others have suggested ALSA may be the culprit, and they may be right, but I have a feeling it isn't. The problem is usually worse when entering live tv mode, and then smooths out, and then occasionally appears now and then. To me it seems like a borderline bandwidth issue somewhere. I think I'll try bumping down my bitrate. I did order parts from Monarch to build a new backend. I'm hoping to use these parts to try and troubleshoot this. If they ever ship.

After a long saga of list-trawling, it turned out to be an error with an uninitialised variable in Myth's ALSA audio module (I so wish C++ would regard this sort of thing as an error). After grabbing a patch from CVS and rebuilding, all is fixed. The patch against 0.17 is attached. Since we have the same frontend hw, I could look into making the (RPM) binaries available if there's somewhere to drop them. Matthew. Thanks for the patch. At first, I thought it worked. When I started live tv, 4 pauses and one underrun where logged, but then it was looking good. That lasted about a minute, and then it was back to the stuttering. It's a little confusing, it does not happen recording a program, and it does not happen when playing a recording, so it's not easy to pin on the frontend or backend. May I ask what kind of tuner card you are using? -Michael __ Do you Yahoo!? Yahoo! Mail - Easier than ever with enhanced search.

I am using ALSA on the frontend, and other than the stutters, it sounds fine. Myth 0.17 The backend is a 400MHz K6-3, 2.6.10 kernel, PVR-500MCE, ivtv 0.3.2p. The frontend is an Epia M10K, 2.6.10 kernel, X.org 6.8.2 with XvMC enabled (and appears to be working from the logs).

[mythtv-users] Live TV stops after a few hours.
Hi! I'm running 0.17, and after a few hours, live tv just stops. I get prebuffering pauses sprinkled here and their when it is working, and then the backend logs: 2005-03-27 17:45:35.038 Changing from None to WatchingLiveTV ERROR: file I/O problem in 'safe_read()': Invalid argument ERROR: file I/O problem in 'safe_read()': Invalid argument ERROR: file I/O problem in 'safe_read()': Invalid argument while the frontend logs: 2005-03-27 19:05:00.495 prebuffering pause Errm, event socket just closed. 2005-03-27 20:03:18.933 prebuffering pause 2005-03-27 20:03:20.755 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:22.756 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:24.758 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:26.760 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:28.761 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:30.763 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:32.765 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:34.766 Waited 2 seconds for data to become available, waiting again... 2005-03-27 20:03:34.767 Waited 14 seconds for data to become available, aborting Freed 5898240 (pool 2) Freed 6428192 (pool 2) Freed 6958144 (pool 2) Freed 7488096 (pool 2) Freed 8018048 (pool 2) Freed 8548000 (pool 2) Freed 9077952 (pool 2) Freed 9607904 (pool 2) Freed 10137856 (pool 2) 2005-03-27 20:03:38.921 ReadStringList timeout (quick). 2005-03-27 20:03:38.921 RemoteFile::Read(): No response from control socket. 2005-03-27 20:03:38.921 RemoteFile::Read() failed in RingBuffer::safe_read(). 2005-03-27 20:03:38.922 RemoteFile::Read() failed in RingBuffer::safe_read(). 2005-03-27 20:03:38.922 RemoteFile::Read() failed in RingBuffer::safe_read(). 2005-03-27 20:03:38.922 RemoteFile::Read() failed in RingBuffer::safe_read(). 2005-03-27 20:03:38.922 RemoteFile::Read() failed in RingBuffer::safe_read(). 2005-03-27 20:03:38.923 RemoteFile::Read() failed in RingBuffer::safe_read(). backend then dies with a segfault.

Re: [mythtv-users] [Slightly OT] Via EPIA, Unichrome, TV-out: Interlacing?
I just asked this the other day, and Simeon Walker provided the answer: Go into 'Setup - TV Settings - Playback' and check 'Deinterlace playback' then select 'Bob (2x framerate)' from the dropdown menu. Worked great for me. -Michael --- Jon Whitear [EMAIL PROTECTED] wrote: I have a Via EPIA M10K front end with Unichrome drivers, using xvmc VLD. In live TV, fast horizontal pans (e.g. Simpsons opening sequence) are a blur, which I take to mean that some form of de-interlacing is taking place. I don't have any interlacing configured in mythfrontend. Is this expected with this combination? Is there anything I can do about it? I'm not sure if this is a Myth issue, or a Unichrome issue, hence my initial post here. Unichrome is from CVS as of February, and Myth is from CVS as of yesterday.
