    I had to recompress XviD .avi (with a troublesome packed bitstream) to DivX so as to make it compatable with my LG LDA-531 DVD/DivX set-top player. When I play the new recompressed DivX file the audio is of by a few sec. I then went into VituraDubMod to look at the video vs audio stream length on the original vs the recomp. The reports read as follows:

    Original XviD .avi:
    ---== Video stream ==---
    Source : [Input AVI file]
    Description : AVI video stream
    Length : 01:42:05.959

    ---== Other stream ==---
    Source : [Input AVI file]
    Description : AVI audio stream 1 [tag 0x2000, ATSC/A-52 (Dolby AC3)]
    Length : 01:40:55.097

    Recompressed DivX .avi:
    ---== Video stream ==---
    Source : [Input AVI file]
    Description : AVI video stream
    Length : 01:42:05.959

    ---== Other stream ==---
    Source : [Input AVI file]
    Description : AVI audio stream 1 [tag 0x0055, MPEG-1 Layer 3 (MP3)]
    Length : 01:42:05.959

    I assume I need to add ms in VDubMod to correct the overage in the recompressed DivX but since this I my first time with correcting audio sync I am having toruble figuring how many ms I should add and how exactly to go about doing this In VDubMod. I would greatly appricate any help whit my problem. Thanks for your time

  2. How about setting the interleaving for the audio track into + or - 169138, depending on if the sound comes before or after the video (your time difference is 00.02:49.138 from what i've see in the report and that's 169138 in milliseconds).
    In any case, i believe you used VdubMod for the whole thing and the desynchronization possibly happed due to the Ac3 audio (those audio files act weird). Try using AutoGordianKnot to re-encode. It's simpler to use and doesn't do any synch problems, from what i've seen that is, plus it's also a freeware.
    Sometimes desychronization is pain to achive because it affects the whole audio file, mp3 in you case. You've got to change the lenght of the whole mp3 and then re-encode it. I believe goldwave using time warp and FFT algorithm can do that.
    Good luck.
