Recently I’ve had a problem with Quicktime throwing up the following error when trying to play a video:

“An invalid public movie atom was found in the movie.”

I’ve searched everywhere for a solution, and couldn’t find one in forums or tech hint sites.  However I think i’ve just solved it – for me atleast.  I just installed VLC Media Player for Mac OS X.  Upon installation, my movies work!  I couldn’t be happier – I think VLC is a little more forgiving if your media format is malformed.

Either way, I can now watch my videos – so I’m a happy camper.
