I recently got a MOV file from a 5D Mark II, which played fine on a Macbook.
I tried to play it on a Windows machine (I don't own a Mac) and I only got a "-2048" error that "QuickTime doesn't understand the file format". I tried installing every codec package I know of and used different players (Windows Media Player, Media Player Classic, VLC...). I did the whole thing on different PCs without success.
On some forums I read that there are problems with playing HD QuickTime under Windows. Does anyone know a solution how I can play that file under Windows? Or at least how I can convert the file to something playable under Windows.
