Hi! I have an AVI file that doesnt play right in quicktime, a message appears telling me that some 3rd party software is needed to play the file and if I click continue it redirects me to a page for 3rd party quicktime apps. The thing is, it does not tell me which app i need. How will I know which app I need? But if I play the file in VLC player, it plays very well.....
just use VLC... if you insist, try downloading PERIAN: http://www.apple.com/downloads/macosx/video/perian.html its free
