I really like the idea of AppleTV, even more so now that comcast is downright ridiculous with there pricing and only getting worse. I have a few questions before I buy... I have an external hard drive, I have several dozen mp4 movies on it. Will this work? And what, if anything, is involved in getting it to work? ...I could of swore I had another question, but im tired and cant think. More to come tomorrow... maybe Thanks!
