Looking at setting up a iTunes based portable home theater system using my macbook (early 2008) and a 19" HDTV. We have a small camper and when we are camping (e.g. no internet); we like to watch movies at night; rather than lugging a TV, dvd-player, case of dvds; it would be nice to just take a TV, maybe a apple TV2, and macbook (always take macbook anyways). I was thinking by using apple TV2, I could connect the apple TV2 and macbook via wireless; thus, we could watch TV outside if we wanted (e.g. leaving the macbook in the camper). Created a network on the macbook (e.g. Wi-fii icon->create a network), but could not get the apple TV2 to see the network in the list of available networks; nor could I manual specify the network name, I would get a network not found. I was able to connect apple TV2 to the macbook via ethernet cable. The issue there is if I tried playing a movie purchased at ITunes store; I would receive an "Authorization Error"; I could play movies that I ripped from a DVD. The other issue is that I am hard-wired; thinking I might as well get a mini-dvi -> HDMI cable and take the apple TV2 out of the picture. So, given that history I have some questions . 1. Am I going about this the right way? Any suggestions? Tell me about your setup... 2. Can I connect Apple TV2 to macbook wirelessly (e.g. no router; rather computer-to-computer)? If so, any hints on what I'm doing wrong? 3. Is there anyway to get around the "Authorization Error" on iTunes purchased movies? I'm guessing this is due to Apple TV2 not having an internet connection. 4. If I go macbook direct to TV; what is the best connection option 1)mini-DVI -> HDMI, 2) mini-DVI -> DVI -> HDMI, 3) mini-DVI -> Composite-Video, 4) mini-DVI -> VGA. TV would support all those options. 5. If I go macbook direct to TV; will I still get the "Authorization Error" on iTunes purchased movies?
