I am struggling with a .mov file that was generated by Final Cut Pro on the Mac, but that I need to play and edit on my Windows PC. Quicktime only plays sound not video, apparently it needs a XDV5 codec that was developed by Apple. Is it available?
Sorry but no; that codec only comes in Final Cut Pro for Mac and, unless something's popped up very recently I haven't heard of, is not available for Windows. The codecs included in QuickTime are listed here:
