Did you try --export_prof dvd, too? I think it's worth a try, because it
sets most of the options to values suitable for authoring DVDs. The
multiplexing remains the same, clearly.
If you absolutely need a bitrate of 4000 Kbps, maybe you still can
provide the -w option, I guess it will override the value chosen by
--export_prof.
For the cutting, have you tried glav from mjpeg-tools? It's simple and fast.
Good luck!

Hi,
i capture some TV broadcasts with my Hauppauge PVR350 and the ivtv driver.
I then cut those sequences with "avidemux2" and write them as AVI, settings
video: MJPEG, audio: WAV PCM.
I try to convert this output to MJPEG compatible DVD with this command:
[1]
transcode -k -i $in -o $out -xlav -yffmpeg,lame -Fmpeg2video -w 4000
mplex -o $out -f8 $video $audio
Playing the output file with MPlayer works fine, but when i feed it to
dvdauthor it complains on every frame:
WARN: unknown mpeg2 aspect ratio 1
WARN: Discontinuity in audio channel 8; please remultiplex input
Playing the DVD on a DVD player leads to missing sound.
I tried to remultiplex this way:
[2]
tcextract -i $in -x mpeg2 > $video
tcextract -i $in -x mp3 > $audio
mplay -o $out -f8 $video $audio
But i still get the same warning and failure.
What do i need to do to get DVD compatible output?
When i use avidemux2 to cut MPEGs on I-Frames i can create DVDs using
method [2]. But when i cut MPEGs not directly on I-Frame borders
i need to output AVI (MJPEG, WAV). Converting this to DVD MPEG fails.
Thanks for any hints,
Torsten.
