But QuickTime *will* tell you what is missing, it just is not obvious or intuitive. Instead of clicking Continue click Cancel and let QuickTime open the file. After that, choose Show Movie Properties from thw Window menu. (Apple- J will also work.) In that properties window, you will see Sound Track and Video Track and possibly some other lines. If your video is playing the Video but not the Audio, check which codec is being used for the Audio. If the Audio is being heard, but not the Video check which video codec is being used. There is almost always a codec available for one or the other, just not on Apple's site. Google it. Then, if all else fails, use Flip4Mac or VLC.
