Alot of the stuff posted here is quicktime for some reason every time I download alot of it I can't watch it, it says 'some files may be missing for quick time' or something like that I can hear it but all I see is white.
If it's a DVCPRO-HD quicktime, those won't play on Windows computers, all you'll get is a white screen. Apple hasn't put the DVCPRO-HD codec into the Windows version of Quicktime.
