    So, I have these videos that will play in the "Get Info" preview window, but when you open them with QT they show up, but if you press play nothing happens. You can advance the timeline and the video moves forward but will not play. I opened it in VLC and it plays but is "smeared". I have Perian installed.

    So, what gives?

    Use VideoSpec, MediaInfo Mac or MediaInfo to analyse that video and attach the report to your next post.
    Also what Mac OS X and QT Player version do you use?

    OS X 10.7.3
    QT Version 10.1 (501.8)

    Neither of those free apps would open the files...and I tried a bunch of them so it is not one corrupted file.

    I attached a Get Info screenshot - again, the preview plays perfectly in the Get Info window.

    That is strange.
    Does it also happen in another, even temporarily created, user account?

    What you have is a DivX-encoded .avi video file, the fact that it has the .mov extension notwithstanding. It may very well be that your file was manually renamed from *.avi to *.mov. Download and install the Perian codec suite. If this does not work, then change the extension of the video from .mov to .avi. And if this does not work, then change it back.

    Tried renaming, no dice. Same thing.

    As I said above, I have Perian.

    I have owned PCs for 24 years. For 23 years and 11 months people have told me "Why don't you just get an apple, you don't have to mess around with all that stuff like you do on a PC...things just work" Well for the last month I have realized that although this $2500 MBP is a really nice piece of hardware, that that is total BS...the its just the same ol' crap only in a shinier box.

    Luckily, I have dealt with these kinds of things for so long, I am willing to keep trying to solve this one...I appreciate the help so far...hopefully someone can figure this out...

    Just a shot in the dark:

    Try installing Quicktime Player 7:


    You'll need to manually open the file from Quicktime Player 7 which you'll find in Applications/Utilites/ after installation.

    I find it surprising that MediaInfoMac doesn't generate a list of the container and codec profile.
