When I rip DVDs they generally have ac3 audio. The internal player
could play a vob file through the PVR-350, but I would never get any
sound. That, now I understand, is because the PVR-350 can only play mp2
audio not ac3. I finally found the tool "toolame" that is designed to
convert a wav file into mp2. So I was able to write the following
simple script that uses mplayer, toolame, tcextract and mplex to convert
a vob file into a mpg file with mp2 audio. Now the "Internal" player in
mythvideo works great for these files through the PVR-350 (no dropped
frames and no audio sync problems). If you have suffered through the
same frustration, I hope this helps ...
#!/bin/bash
mplayer -vo null -ao pcm:file=$1.wav $1.vob
toolame $1.wav $1.mp2
tcextract -i $1.vob -x mpeg2 > $1.m2v
mplex -f 3 -o $1.mpg $1.m2v $1.mp2
rm -rf $1.m2v $1.wav $1.mp2
