    I recently upgraded VLC and Quicktime, and now older AVI files that have been previously playable are not. This is not ALL of my previously-working AVIs-- but a lot of them, for sure. I have tried deleting the VLC folder and VLC prefs .plist file from the LIbrary folder, and downloaded and installed Perian.

    I usually just open all my movie files in VLC, but when I try these older ones they either don't work or play what I believe to be a random song from my iTunes. When I try to open them in Quicktime, I'm given a OSStatus error -50.

    Any help would be VERY, VERY appreciated.

    First thing I would try would be to revert to an earlier version of VLC.

    How do I even discern codecs? Like, is there an index of installed codecs on my computer I can look at somewhere? How would I look at a movie file and discern what codec it was in? Sorry for all the questions...

    Alright, just did it. No difference, sadly. :confused:

    With the video open in either the QuickTime Player or VLC, press [cmd]+[ i ].

    Okeydoke, here's an example. It says MPEG, looks like:

    It looks as though the only AVI files I can play are the ones using the Xvid codec.

    Hi, try the free program D-Vision 3, on the tools you can change the codec to xvid, hopefully you'll be able to trick vlc with that...
    good luck!!!

    I believe I do-- at work at present. It's never caused problems in the past, and I think I downloaded it and then never used it.

    I think I'm having the same problems. I upgraded VLC to v1.0.1and now it won't play my movies, I've only tried a couple FLV files however they DID play b4 on the previous version of VLC.

    Does anyone know why? Anyway I reverted back for now but would still like to know what's causing the files not to play on the new version.
