Re: [mythtv-users] Dual processor any help?
I'll throw in my 2 cents about topology, and let someone else answer the exactness based upon Myth software itself (although it's likely that Myth isnt multi-threaded, but it's possible, so someone else pop in on this). 1st, will it reduce your transcode time... if you were doing 'other' things on the box at the same time.. then the easy answer is yes, it will have some benefit. i.e. if you were trying to watch something on the FE at the same time you had the BE doing the transcode, then yes a dual CPU setup will help your speed and/or remove jerkyness of the FE. However... it wont be 2X as fast by any means... This comes down to if the Myth modules are multi-thread away... I wouldn't think-so... but we can both hope someone will respond. :-) Btw, if you were not 'doing anything' else on that box, at the same time you were transcoding, and someone responds that the Myth modules are not multi-threaded... then you will still see some speed increase, be it moderate, because you have 1 CPU dedicated to the transcode, and the other, is running the OS, handling memory, disk IO, network IO, etc... -Michael On Sat, 15 Jan 2005, John Williams wrote: > My myth FE/BE combined is a dual proc Intel P3 capable machine.

DVD as backup to avoid delete button WAS: [mythtv-users] What NOT to do to your Myth box...
Since I see that the original thread has been hijacked into create ways to recover the data that was lost... It seemed like many people were advocating transfering files to DVD, with perhaps the preferred method as fully authored DVDs. This brings up the issue I would love to know the answer to in mass which is... Are you doing: 1. Did you buy a $1k to $8k DVD Jukebox w/FireWire connect (http://www.powerfile.com/) to your Mythbackend as pure mythfiles? (not using fully authored DVDs) 2. Did you putting the new DVD on the shelf, and put it into your DVD player (set-top or mythtv frontend) to replay the disk? 3. Did you buy an off the shelf DVD jukebox (Sony 200 or 400 capacity)? Paul below says he did a direct connect to the TV input... Has anyone got this setup working to the Myth Backend with/any existing Myth plugin? -Michael On Fri, 14 Jan 2005, Paul Kidwell wrote: > > -Original Message- > > From: Michael > > > > After you have finished the what appears to be a monumental set of tasks > > to get the DVDs authored... > > > > How to you access them?

Re: [mythtv-users] What NOT to do to your Myth box...
After you have finished the what appears to be a monumental set of tasks to get the DVDs authored... How to you access them? Do you just store them on the shelf? I myself was hoping for a solution to use cheap off the shelf Sony DVD jukebox - 400 DVD (1.56TB capacity - for $300)... that could be fed into the Myth backend, somehow... but havent seen any response on a previous thread. Many have also mentioned doing RAID, but this only helps in the case of HDD failures... As noted by this thread, there are plenty of ways to accidently delete or corrupt your data. Thoughts? -Michael On Fri, 14 Jan 2005, Scott Alfter wrote: > On Fri, Jan 14, 2005 at 04:44:51AM -0600, John Williams wrote: > > >I've gotten fairly good with a handful of Windows > > > programs that make DVDs out of stuff ripped from my TiVo or my MythTV. > > > > What programs are you using for your windows archiving? > > I usually start by splitting the audio out of the MPEG program stream with > DVD2AVI and decode it to WAV with LAME.

Re: [mythtv-users] OT: LVM, partitioning over multiple drives
RAID5, is simple math "x + y = z", therefore the min is 3 drives... But you lose 1 disk in the process... so 3 disks = lose 1/3rd... 4 disks = lose 1/4th... etc... the max num of disks depends on the HW controller, or for Software RAID on linux I dont believe there is a limit. Obviously your usable space, gets better with the more drives you have... Also RAID5 has very good read performance with larger block sizes, which should do very well with large files... like video! yeah! but RAID5 write performance sucks, because it takes a fair amount of CPU to calculate the "parity" (redundancy info) bits, during a write operation. (which is why most servers doing RAID5 have their own CPU on the HW raid card + memory to buffer the write operations). Now if you have a dedicated FileServer, that isn't also your Myth Backend, then it may be fine using Software RAID... and it would be the cheapest way to get a large volume + redundancy. -Michael On Thu, 13 Jan 2005, Les Gondor wrote: > At the cost of the aggregate space not being the sum of the capacity of > the individual drives, the only way to get complete fault tolerance is > to make the volume a RAID-1 or RAID-5 configuration.

[mythtv-users] MythTV w/HD Sat or Cable? what hw to use? is the dolby preserved?
Has anyone gotten a MythTV box, running with an external tuner, pulling down HDTV signals from either Sat or Cable? If so, what are you using to pull the feed into the MythTV backend hardware wise? (i.e. how are you getting the "Dolby Digital COAX or Optical" + "S-video/component video" into the PC?) Also, can the full Digital Audio (5.1) information, then be played back on a remote MythTV frontend? -Michael ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] DVD carousel or lots of HDD space?
The PowerFile C200S is the only one I've seen. 200 disc's w/1394 firewire connection for about $1000 or the dual drive for $2000. http://www.publishingperfection.com/powerfile/storage/24/ Which is why I'd rather do a regular DVD jukebox, 400 disks for $300... maybe I should just ask the question about streaming, as this appears to be my real question. -Michael On Mon, 10 Jan 2005, Robert La Ferla wrote: > Sorry, no answer but I have a related question: > > Are there any DVD jukeboxes that have a ATAPI/SCSI interface for say > less than $800? > > ___ > mythtv-users mailing list > mythtv-users@mythtv.org > http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users > ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] DVD carousel or lots of HDD space?
Hey Brad, thanks for the info... Although I was also trying to avoid the eventual HDD crash condition as well... hence why I was going for the more permanent solution of moving to DVD-RW. As for MPEG4, from what I've seen on the web about it, I dont think it would deal well on my end... I have a 45" big screen, and I can tell the difference between my Dish Network 301 receiver with it's compression, vs. my C-Band dish w/o compression. Digital artifacts drive me nuts... so I was planning on leaving everything in MPEG2. -Michael On Mon, 10 Jan 2005, Brad Templeton wrote: > On Mon, Jan 10, 2005 at 03:52:04PM -0800, Michael Miyabara-McCaskey wrote: > > > > I'm thinking of setting up a system, that can use a Sony DVP-CX985 - 400 > > DVD jukebox ($300), as it's primary method of archiving recorded TV + > > playing existing DVDs...

[mythtv-users] DVD carousel or lots of HDD space?
Hail Mythtv gurus, I'm a total newbie to the world of PVR's and I've found only documentation on HOW to do something with MythTV, I havent found anything on WHAT to do with MythTV... So... Here goes... I'll get my fireproof suit on now! :-) But please tell me if I'm being silly or not on each option. I'm thinking of setting up a system, that can use a Sony DVP-CX985 - 400 DVD jukebox ($300), as it's primary method of archiving recorded TV + playing existing DVDs... (as I'm trying to avoid buying several terrabytes of HDD space - as I have a collection of several hundred DVDs today). Config#1: Basic PVR w/glorified frontend maybe? - Sony DVD connected directly to TV/speaker input#1. - Dish Network connected directly to MythTV host. - MythTV connected to TV & speaker system on TV/speaker input#2. - MythTV external receiver IR blaster to control Sony DVD. Question on this option: Can MythTV be loaded with a list of the DVDs that I put into the Sony DVD player? From what I have read, the "MythVideo" module, is what would be used to play these back, as well as annotate the IMDB info on each line item... Can "MythVideo" act as a pass-through IR blaster? PROs: * DVD-RW media is cheap plus no crashed HDDs to worry about. * Video & Sound go direct to TV, so quaility should be great. CONs: * Dont know if the "mythvideo" module can work as a dummy pass-through of IR commands to the Sony DVD player. * In this method no additional TVs can use the video on the DVD player. * Dont know if I could get the IR blaster to change my inputs correctly. * Just seems cludgy, just doesnt sound like a MythTV setup. Config#2: Streaming through MythTV w/Dolby Digital? - Sony DVD video connected directly to MythTV capturecard#1 (s-vhs). - Sony DVD audio connected directly to MythTV soundcard#1 (dolby coax). - Dish Network connected directly to MythTV capturecard#2. - MythTV connected to TV & speaker. - MythTV external receiver IR blaster to control Sony DVD. Question on this option: Can MythTV take video from 1 card, and sound from another card, re-integrate into a stream, and fire it back out to the TV and speakers still including the Dolby Digital? Also same question as in config#1 above. Sounds Card: Creative Labs Audigy 2 ZS Platinum?? cuz it has lots of in/outs for Dolby Digital. Capture Card: Something that can handle 2 - sources?? or just buy 2 cards? any recommendations as to which one(s)? PROs: * DVD-RW media is cheap plus no crashed HDDs to worry about. * Only need the TV/Speakers on 1 input source forever CONs: * Dont know if the "mythvideo" module can work as a dummy pass-through of IR commands to the Sony DVD player. * In this method no additional TVs can use the video on the DVD player, unless streaming can be done from MythTV backend to frontends... which leads to config#3. Config#3: Streaming w/Dolby Digital to MythTV backend. Playback on at multiple locations? - Same as above, except pretend I split just the "MythTV connected to TV & speaker" to 1 or more hosts. Question on this option: Can the streaming be done to a MythTV backend and therefore a MythTV frontend can pick it up? and if 1 frontend can pick it up, can several pick it up via multi-cast or something similar? Dont you guys love newbie questions? Thanks in advance for any info you can give. -MyKarz ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
