I'm using mjpegtools-1.6.1.90
Either i'm not interpreting the docs correctly, or -O does not work as
expected.
I multiplex a VOB without -O:
mplex -f 8 -S 500 stnem.m2v stnem.ac3 -o stnem2.vob
Then i mux another one, this time with -0:
mplex -f 8 -S 500 -O 500 stnem.m2v stnem.ac3 -o stnem.vob
However, neither xine nor mplayer show any differences in A/V sync when
playing these VOBs. It's like -O has no effect.
tcprobe (of transcode-0.6.11) probes correctly the VOB created without
-O and it shows identical PTSes for video and audio, which is the way it
should be:

However, when i run tcprobe on the "-O 500" VOB, the results are kinda
weird (look at the PTS values):
