Playing a avi format

Try downloading Flip4Mac

AVI isn't a format; it's a container, and some AVIs require codecs which aren't available for Mac OS X. Try using Perian or VLC.

Just like Sanjampet said, download Flip4Mac or the popular VLC as it can play mose media formats. Niel is correct, as Apple does not support the necessary AVI codec.

just download VLC for Mac, its free, .....Ive yet to meet a Mac user yet that doesnt have it installed.

Likely the only APP I could say "everyone has it"
