I'm setting up my old Apple TV 1st gen in my house. I've been encoding all of my movies for the ATV2 using Handbrake's ATV2 preset. My Apple TV 1 sees all the videos in my iTunes but can't play the ATV2 encoded videos. Is there a reason for this or a way around it? I don't see why I shouldn't just start using the ATV1 preset if the ATV2 can read ATV1 encodes but I also don't understand why it's not working the other way around. They're technically both capable of playing the same videos right?
