Can I watch movies with an ATV that are in my movies folder or can I transfer movies via my wireless network to the ATV hard drive and watch them? I want something that will let me watch AVI files like FrontRow does. Will ATV work? If not, is there a hack? Any other ideas? A MacMini seems like overkill for what I need and I don't want to have to convert all the AVI files to iTunes (a major pain).
