Long time reader, first time poster. I have installed XMBC (and Boxee) on my Apple TV. I am trying to stream movies from my iMac to these programs, but I can't get either one to play Avi/DiVX files. I can get them to add the iMac as a source, play music/view photos that are in my shared folder, and list off the movie files I have. They play in quicktime on the iMac, so I don't think they are corrupt, but won't play in XMBC nor Boxee. I did a factory reset, and reinstalled from the patch stick but still no luck. Needless to say, I am quite frustrated. Any suggestions?
