    Today I noticed that play certain mp4 movies in my Quicktime player. I can hear audio but I don't see video.

    What is so strange about it that until today I was able to view them without any problems.

    I still can watch them with VLC player.

    How can I solve this problem? I am using OS X 10.6.3

    Which QuickTime player has this problem?

    QuickTime X or QuickTime 7?

    Did you try to repair permissions via Disk Utility, and did something happen between the ability of playing .mp4 files and the current disability to do so?

    It's Quicktime player X, version 10.0 (113). I didn't try to repair permissions or anything like that.
