An MOV file is a QuickTime media container format.

If you’re on Windows, I’d actually say don’t use QuickTime if you don’t need it. It’s intrusive while not giving anything that other players don’t. However, it rocks if you’re on a Mac.

But overall I second the vote for VLC Player. I even use it on the Mac.
