I have the unibody MBP, 13 in., all software up to date, purchased in June 2009. I also have an iPod Touch and iTunes. Yesterday I bought Apple TV after asking about a way to view my MANY photos on our TV. My spouse, a PC user, was excited about all the possibilities. Well, it isn't what we thought, but for sure the photos look great. A couple of problems, though. I signed in to my Mobile Me account on my computer, but when we tried to enter it on the TV screen/Apple TV, it kept saying that was an unknown Mobile Me member. Also, the computer and TV seem to be on completely different photos. I know this isn't like an external monitor, but can't figure out why I have one slideshow going on the computer and one on the TV. I tried to do a search for a tutorial, but didn't find one. Any advice would be welcome. Just so you know, we thought we'd be controlling the TV with the computer keyboard, but you have to use the remote that comes with it and entering names and passwords is a pain.
