there is NO such info in the mpeg headers

maybe it is in the .ifo, but no one has detailed docs on .ifo file format
the current rev.eng.-ed docs only cover navigation

i have only 3 dvd disks, and none of them has such problem
so eirther teh disk is badly mastered, or i'm just lucky...

send me such disk with this problem than i can probably reproduce and try to
find where is such info stored...

anyway i still say that it's probably audio driver problem
mpeg files has exact timestamps on both video and audio, and i've never
heard about constant a-v offset used in mpeg files or dvd disks
so, the only way to get a-v desynced is bad driver of slow system
