I do not understand the final warnings. When I run this command there
is no sync-offset at all.
Alternatively, if I use mpgtx to add 6 seconds of silence to the mp2 file...
SYNC_SEC=6
perl silence.pl ${SYNC_SEC} silence-${SYNC_SEC}.wav
mp2enc -o silence-${SYNC_SEC}.mp2 silence-${SYNC_SEC}.wav
mpgtx -j silence-6.mp2 ST.mp2 -o ST-sync.mp2
And run mplex...

Despite mpginfo displaying that the file is full and VLC/mplayer/etc
being able to play it fine.
Recommendations for either method would be greatly appreciated.
