I've used dvd::rip to encode some movies from dvd into ogm files with xvid codec for video and vorbis for audio (some using quality = 3, some with quality = 0). It seems that the audio starts in synch, but it'll gradually lag behind the video more and more. Another movie encoded with mp3 CBR (avi container) has no noticeable audio lag for the entire movie. What can I do to keep the video and the vorbis audio in synch when using the quality mode ? I have not tested encoding the movie with vorbis in CBR mode yet. Thank you. __________________________________ Celebrate Yahoo!'s 10th Birthday! Yahoo! Netrospective: 100 Moments of the Web http://birthday.yahoo.com/netrospective/
