QuickTime won’t play my video
With the announcement that the developers of Perian are to discontinue their QuickTime plug in, it’s probably time you switched to using the open-source video player VLC.
Not only does VLC play video files that QuickTime can’t play even with Perian, it will also attempt (and often succeed) to play files that suffer from minor corruptions.
If you’re having problems playing a video file in QuickTime, chances are VLC is the answer.

Apple discontinued support for quicktime 😦
My Macbook will play .mov files through VLC but not Quicktime. Quicktme stopped working after I upgraded from Leopard to Snow Leopard. Any ideas on how to fix that? Thanks in advance.
