    I have this xvid file with variable bitrate mp3 audio and pal framerate that was both getting me errors on mediaplayer classic and getting out of sync when trying to convert it to dvd through different means ( dvdsanta, dvd2svcd using cce and the film machine also using cce ).

    So i followed the suggestion on the sticky and changed the audio to constant bitrate mp3. Since it was still out of sync i followed another suggestion i found here and used virtual dub to get the audio on sync since it was only displaced. Now i have a fixed avi file with constant bitrate mp3 audio that has audio in synch but whenever i try to convert it to dvd or mpeg2 ( with dvdsanta, dvd2svcd + cce and thefilmmachine + cce ) the audio still gets out of synch ( but not by as many second as it was before i used virtual dub to introduce a delay ).

    What else can i do to succesfully convert this file to mpeg2?

    Rip the synced audio out to .wav in virtualdub.
    Encode the avi video, and use the .wav as the audio source.
    This should produce an in sync mpg.
    The problem lies with mp3 audio. Even though you now have sync, encoders just don't deal with it well.

    Ok i ripped the cbr mp3 audio from the fixed avi on virtual dub and used winamp to transform it to uncompressed wav and when i tried playback on mediaplayer classic and using wav audio on virtual dub the audio was out of sync again.

    So now im using virtual dub to resynch the now uncompressed wav audio to the avi since its apparently the exact same delay needed ( 8700 ms ) and see how that works.

    Why would you use winamp to uncompress it?
    In virtualdub, select audio, full processing, file, save .wav
    Once you have the .wav and the video, you can test in vdub, and adjust as needed, then frameserve it. Easier than saving file after file in vdub.

    I tried with virtual dub and when i saved the wav in full processing mode it was still out of sync, but after i corrected the timing and saved the avi i was able to succesfully create the dvd with sync audio.

    Thanks alot for the tips! :D
