    Trying to letterbox an XVID .avi with audio passthrough, I'm getting fast scrolling error messages [hundreds of them] as above. Any attempt to reencode audio on the source leads to loss of synch.

    Get Info on source:

    "VIDEO: [XVID] 640x272 12 bpp 23.976 fps 789.2 kbps (96.3kbyte/s)
    audiocodec: framecopy (format=55 chans=2 rate=48000 bits=0 B/s=15880 sample=0."

    Any attempt to extract an mp3 from the avi leads to a shorter file - out of synch. Burning subs on older binaries failed to synch the subs too, though they burn fine on the newer binaries (at mencoder default only - a known limitation).

    Anyone have any ideas why this happens and how to work around this?

    Process Information: "error, non monotone timestamps nnnnn >= nnnnn" where n=a number

    Seems like an ffmpeg bug.

    Workaround is extract the sound.
    Do the encodings without sound.
    Adjust the mp3 manually to synchronize (I added/subtracted blank spaces in Amadeus).
    Mux the video and sound file in the Tools pane as .avi.
    Et voila!

    I would suggest to try some other tools to rebuild/extract the tracks before processing the video track.
    With D-Vision, you may try :
    - rebuilding the movie (tools > .avi and .mpg re-encoding panel > copy/extract tab)
    - extracting audio and video stream

    You can also try avidemux.

    Thanks for the info, Jean-Philippe, will see what D-Vision does.

    D-Subtitler, I don't use: can't convert idx/sub to .srt, and doesn't even have a [Renumber Subs] button. I drop mine on a spreadsheet for renumbering, flagging overlapping times, and dialogs that are too short.

    avidemux download is in unknown format for me.

    If you get a .dmg.bz2 file, rename it to straight .dmg before double-clicking it. I think Safari already decodes .bz2 on the fly without removing the extension. Then if you were opening the file with BOMArchiveHelper (Mac OS X included archive helper) it would try to decode an already decoded file, thus resulting in file corruption.

    Thanks for that. Filename extension was truncated to d.bz2 - renaming to .dmg or .d.dmg failed to work. Renaming to .dmg.bz2 did the business. X11 launched after a cryptic dialog box saying I already had a ~/xintric or something and would I like to set it aside? [I clicked No] and aviddemux launched and extracted a problematic audio file - 11MB of mp3 from a 181MB .avi almost instantly.

    (Just for the record)
