Does anyone use the TSU3000 with MythTV that has a screen they want to share? Remote central didn't have one so I thought I'd check here before I created one from scratch. Thanks, Todd ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
Re: [mythtv-users] Re: apt-get on FC3 still broken?
I'm coming in late to this thread, but this weekend I installed FC3 (several times in fact) without trouble. I let up2date upgrade the distribtion and just used apt-get to install the mythtv-suite. The backend I left at 2.6.9 since the upgrade to 2.6.12 didn't seem to include the source I needed to compile ivtv. The frontend I let up2date upgrade to 2.6.12 and it's running smoothly. - Todd Quoting Evil Barney <[EMAIL PROTECTED]>: > I tried this with a fresh load of FC3.

Re: [mythtv-users] What's a good mini front-end-only box?
I have only tried it on a very limited basis and the audio was way out of sync instantly and haven't gotten back to debug it further. I did rip the 5.1 sound track in Myth, but not sure if I marked the AC3 box at the time. I don't know how what formats are decoded and where, but my laptop plays DVDs (myth and Windows) just fine so I assume the player is decoding for me or something similar. Sorry I can't provide a more knowledgeable answer, but how the audio streams are handled is beyond me. - Todd - Original Message - From: "Mudit Wahal" <[EMAIL PROTECTED]> To: "Discussion about mythtv" Sent: Thursday, July 14, 2005 5:09 PM Subject: Re: [mythtv-users] What's a good mini front-end-only box? Todd, How are you watching DVDs ? MVP doesn't have a dolby digital 5.1 decoder. Almost all dvds are encoded in 5.1. So are you re-encoding/downmixing the sound to 2 channel stereo ? Or you dvds have 2 channel stereo option. When I tried to play some VOB files (renamed to mpg), I was able to watch DVD but no sound came. I also recorded programs from my HD3000 card. I had to downres to 720x480 and to 2 channel stereo using vlc in order to watch them via media mvp.

Re: [mythtv-users] What's a good mini front-end-only box?
It's a great light weight front end. Google Myth MediaMVP for the site. It loads a myth image via tftp from the myth server. From there you can watch recorded TV shows via the myth protocol or video via an NFS mount (scripts exist to make a friendlier name).
