I'm trying out DVDFab 22.214.171.124 with National Treasure 2 (PAL).
When trying the following options:
DVD to Mobile
XVID with mp3 option (2-pass encoding, 192k audio output)
Extract subtitle/idx to separate file
This a/v sync issue was mentioned as fixed in 126.96.36.199
Issue: The whole process took approximately 6 hours (Pentium4 2.4Ghz) and the resulting file had the audio out of sync with the video (it was fine for the first ~ 90 minutes, but deteriorated to the point where the audio continued approx. 30 minutes after the video finished).
I tried the same options with DVDFab 4 which took approx 3 hours, but also resulted in an audio/video sync problem (not as bad as 188.8.131.52).
