So, currently I have a Mvix external HD box that I put videos on to watch on my TV. However, I'm getting to the point where I don't want to move everything over to that external HD to watch it, and I'd rather just keep the videos on my computer and stream them to my TV. So, can an AppleTV just stream from a single iTunes library, or would I have to go and set it up to stream from iTunes a single video at a time? Basically can I view my iTunes library from AppleTV? Also assuming the connection is strong enough (wireless n/g or wired) is the quality comparable?
