Hello everyone I have a problem and wondered if anyone can help please. I have just purchased a Canon digital camera with a movie function which seems to save in .mov format. Not a problem as such but all my previous video files are mpegs which come from my Sony handy cam, I haven't installed any software for the camera I've just put the SD card into my PC and copied files onto the HDD. Suddenly all my mpegs will only run the sound track in media player although the mov files run fine, I don't really know whether it's anything to do with the new camera files but I've only now noticed it when trying to view one of my mpegs. When I had XP media player would never run mpgs claiming it needed a codec, after allowing it to download the codec it would only play the sound with a visualisation, I had to us VLC player. I don't really want to go down that road again, if anyone can help I would be grateful.
