I have a problem which came up just a couple of weeks ago, maybe because of the update of Perian! But I am not sure. I have some 720p mp4 files on a external harddrive which used to play but then all of a sudden ATV files and nitoTV are not able to play these files anymore. When I click on them either the screen turns black and the finder restarts or the AppleTV freezes with a black screen and I have to restart the AppleTV manually. This is really annoying because the used to play!
Does someone have an idea of how to fix the problem? Can I go back to a previous version of Perian? Is Perian causing the problem?
Thanks a lot for any help...
