My hubby just bought me a sweet digital camera for Christmas after buying me a new computer just the month before...New computer has Vista on it and the new digital camera records video files in the .MOV format. When I try to play the video files with Quicktime, the player errors out and then can't reopen the video. So, I allowed my ever trusty Windows Media Player to do some "media changing" and play the .MOV files for me...All was going well on the first viewing then the video started speeding up, then the sound went out and then my computer locked up, shut down and had to go through the whole scanning my disk drives process. Is there a known issue with .MOV files and Vista? Or with Vista and Quicktime?
