Hello. I am stating to get a pretty good collection of t.v. shows and want to start on getting some movies on iTunes. Right now I am playing them off a lop top (not mac) and a cable to my t.v. The computer non-sync and stalls sometimes. Would this be fixed with Apple T.V. or does it have something to do with my band with and Apple T.V. would not matter? Also, can you have more then one Apple T.V.
