I cannot get the AVI files to play on my iMac. They were copied over from the PC and I can see them but when trying to open them I get the message "The document “Mural.avi” could not be opened. A required codec isn't available." As far as I know I have the most recent version og Qucktime.
iMac, OS X Mountain Lion (10.8.4)
