I've brought all my stuff over to lion. Mostly all my various video files work fine. Sometimes there's a problem with the new QT player but either the old QT player 7 or VLC or MX player will work. However I have a small bunch of important files which were saved as .mov files in the old QT player 7, and they will not open in anything. I get a message saying something about WMV3 codecs. Anyway I downloaded the Divx codec which stopped the new QT from working at all, so i trashed that, I remembered that I onced bought easy WMV so I was able to download that which didn't work, flip for mac didn't work either. I was just about to give up when I accidentally dragged a file into a Safari window and it played fine. So now I'm wondering why I cannot play the file in either the new or old QT player, but it will play in the Safari window and the FF window. What is going on here. here is an error message from VLC thanks.
