I just installed OS X Lion but when I try to open any AVI video with Quicktime that reads "The Document <filename> could not be opened. A required codec is not available." I clicked the "Tell Me More" button and I redownloaded the DIVX codec but my files still don't open with quicktime. Is it possible that my codec is not compatible with Quicktime for Lion? But then again the Quicktime application is still the same, it hasn't been updated since Snow Leopard. Is anyone else encountering this?

divx might interfere with perian because perian already covers divx and xvid. Only one solution, not both..


simply uninstall every 3rd party codecs you have installed and go with just one if there are more then one to choose from.


Perian and WMV ( flip4mac ) is all I have on Lion and it plays everything, even downloaded youtube videos ( flvs ), the videos my Samsung mobile phone makes and the strange encoded avis that my sister sends me via email from her vista machine.
