I use MythBurn. It's a patch for the MythWeb www interface, along with
some shell scripts.
Basically, it does my commercial cutting, transcodes to AC3 audio, and
burns the resulting
mpeg2 directly. There's no video transcode necessary. In fact
(disappointing, actually) MythBurn
isn't even capable of transcoding video. So if you use it your videos
MUST be in mpeg2. Bummer.
I'd like to transcode my mpeg2s to mpeg4 to save spave and still be able
to burn them, but oh well.
