I've been trying to get Perian to work in Lion, basically QuickTime simply refuse to play any files other than the standard QuickTime supported file types (Perian is supposed to add this functionality).
I tried uninstalling Perian and installing it again, but doesn't seem to be working. From a quick google search it seems that so many people has this problem, and some of them seems to get this working again by reinstalling but I didn't. Anyone got any ideas how to fix this?
Edit: I found the ticket(http://trac.perian.org/ticket/622) and the developer says that this is not Perian bug and they won't fixed it.
