Okay I want to be able to stream movies through my xbox or my ps3 from my iMac. I have connect 360 and Medialink which work great. My problem is getting certain formats to work. I converted some movies in itunes but I lose the audio. I have downloaded movies from Itunes and the xbox says it cant play the file. Is there anyway to convert Itunes downloads? And what format should I be using for the video part to stream everything correctly and so I can get a better than ipod quality video??
