Looking into ways to do screencasts from Linux I tried Wink, Istanbul, and Recordmydesktop. My requirements were that I could record both video and audio within the same tool. Wink 2.0 isn’t released for Linux yet and it’s the first version to support recording sounds, Istanbul tried to record but didn’t save the sound (and never really wrote the entire file out), but Recordmydesktop did it’s thing beautifully.

XvMC, MythTV, and my nVidia Geforce 7300 GS
I got some pointers from http://www.mythtv.org/wiki/index.php/XvMC for my Kubuntu Gutsy-based MythTV box and wow, the CPU usage dropped way down.

Burning pcHDTV HD-5500 Content to DVD: Authoring
Most DVD authoring software likes to have the audio and video in separate streams. No problem. I used TMPEGEnc to demux the mpeg 2 and the AC3 audio through it’s MPEG Tools found on the File menu. (I’m sure there’s a way to demux during the mencoder step but when I searched the man page for ‘demux’ I found way too many options and I’m being impatient.) Important update #2 below; no need for demux.

Burning pcHDTV HD-5500 Content to DVD: Transcode
I’m still in the middle of the transcode from the ATSC broadcast mpeg encoding (which I’m not sure what it is, but I haven’t really looked into it) to VOB mpeg2 so I can write a show I recorded to DVD. But so far it seems to be working well. I tried all sorts of windows tools, and I’m thinking I could have gotten avisynth to work, but it was much simpler to use ffmpeg to fix it up. ffmpeg didn’t work so well. Update below.
