I'm late to this thread so pardon me if I misunderstand. I burn videos
recorded on mythtv to DVD with dvdauthor. To do so, I first process the
video with 'mythtranscode --mpeg2'. Then I demux and remux the audio and
video with this script:
#!/bin/sh
infile=$1
outfile=$2
tcextract -i ${infile} -x mpeg2 > movie.m2v
tcextract -i ${infile} -x mp3 -a 0 > movie.mp3
mplex -f 8 -o "${outfile}" movie.m2v movie.mp3
If I don't do both steps in this order, frequently dvdauthor errors out
when processing the video.
Hope this helps.
