Hey Everyone,

I have a series of .avi files that, up until recently, I was able to watch using QuickTime and on my television through my EyeHome box...

Due to a hard drive failure, I had to copy these files to another hard drive. Now when I double-click on one, I get a message from QuickTime stating "The movie could not be opened. The file is not a movie file."

Meanwhile, though, I can still play these same files using VLC Media Player. So what gives? Why would files that were previously playable with QuickTime suddenly stop working?

Yes - I've got all the latest software updates, etc.

Any ideas?


G5, Mac OS X (10.5.2)

    can you open them with mpeg streamclip? and then convert them back?

    maybe they got corrupted during the transfer. or u r missing some playback component on the newer system.

    I, too am having similar problems. I had upgraded to QT 7.4 and my FCP 4.5 would no longer launch. I Archived and Reinstalled my osx 10.3.9. Now, all my MPEG-1 files that were previously useable in QT give me the "The movie could not be opened" message. The video is viewable in VLC, however.

    I do have QT Pro 7. I cannot use MPEG Streamclip. When I try to open with MPEG Streamclip, I do not get any video.

    I have purchased the Apple QT 6 MPEG-2 PLAYBACK, but that didn't help. I don't know if there is a playback component I had before that I don't have since the Reinstall.

    Any help would be appreciated.

    I started getting this error after I took the latest QT upgrade (7.4.5). I restored version 7.4.1, and everything works as before.
