[MPlayer-users] A/V Sync Problems

> audio track (aid 128) works fine with the same commands and videofile by

>
> There seems to be some automatic correction when playing the dvd
> directly and I wonder how I can consider this information when

> Extracting with transcode 1.1.2 leads to the same results by the way.

> Thanks for any help on this.
