I am new to the world of apple tv so I apologize if some of this has been discussed before. Most of the tv that I watch comes from downloading torrents (usually avi or divx files.) I'd like a way to watch them on my tv. I know popcorn hour is great for this, but can a hacked ATV do all of that plus allow you to rent movies? Can I watch all of my avi downloads stored on my external hard drive and watch it on my HDTV via a hacked ATV? If so, is there any advantage to hardware like popcorn hour? Also, is there a link to an up-to-date guide on getting an ATV to play non-itunes compatible files?
