    I have tried to append a two-part div3 movie in Virtualdub but came up with an error telling me the videos had different stream rates (25.119 vs 25.11869). Odd. So in vdub i forced part 2 to recalibrate to 25.119 as well. Yet, when I attempted to append a second time I got the message again, but this time indicating the different stream rates as 25.119 vs 25.119. Huh? In Gspot, as well, the two files seem identical. What gives? Thanks

    Hmmm, that's harsh eh? I guess if you took the framerate to 5 decimal places (like that 25.11869) then the framerates are still not the same - it knows they're different.
    Is that what you're talking about, framerate? Or streamrate, what is that, like the bitrate?
    Surprised you didn't get audio error, your audio must be CBR MP3.
    My framerate (NTSC) is 23.976 so I just thought you were a PAL person. But streamrate, I dunno.
    You could author a compliant DVD from the 2 AVI segments, and it would convert and append them nicely - I would use my NeroVision Express 3.
    I hardly ever convert AVI to DVD, but yours is an unusual problem...
    Regards

    Did you try to go, in VirtualDub, to Video___Frame Rate and, in the Source Rate Adjustment, change the frame rate of the second AVI file to, say, 25.119?
    In this way the framerate of both movies shoul get equal and you shouldn't have a desynchronization you can detect (you would detect if if you changed it, say, from 25 to 23.976; but if you change the framerate from 25.11869 to 25.119 you shouldn't detect it.
    If the A/V synchronization could be detected, you could modify both the audio framerate (BeSweet+GUI, OTA options, format: MP3 CBR) and substitute it in the AVI using VirtualDubMod (Stream___Stream List ; disable the new MP3 CBR stream, add the new one.

    Ah, remember: since you're just adding frames, set Video to [bold]Direct Stream Copy[/bold], so you won't spoil at all the video quality (you just have to be careful to avoid spoiling the A/V synchronization).
