Tried for first time to rent movie from ITunes on Apple TV (Gen 2). We have a wireless internet connection that can be problematic at times so rented movie on Thursday evening with expectation that it would download and be stored on the 8GB (I'm told) of internal Apple TV flash storage. One HD movie will fit there.
Next morning, checked and Apple TV said it was ready to play the movie. The terms of rental are you have 30 days to watch the movie, but once you start it expires in 48 hours.
Friday evening, start Play. The 'Loading *' message appears, then changes to
600 minutes remaining, then 853 minutes remaining. Watch this for a few minutes and decide we aren't watching any movie this evening.
Call Apple tech support, and while on hold peruse the apple discussion forums. Seems I am not the only one with this problem....
Apple tech asks a few questions, then puts me on hold. Comes back and says I need to talk to the senior tech rep (after only 3 questions

). He comes on, I explain the problem, mention the apple support forums and the threads on there; all he wants is the URL to the apple support forums and gives me a case number.
I ask about refunds and he directs me to the Itunes store where after some head scratching I figure out their user interface to report a problem. [Clue: the 'Report a Problem' column that appears after pressing the 'Report a Problem' button beside the movie is a NON underlined Live Link that you need to click to actually type in the problem report]
3 email exchange later with Itunes store the following day, I am told I will get a credit... I had to quote the case number I received from apple tech support to reinforce my point..
It will be a while before I try to rent a movie again - probably not until an update appears for the OS on the Apple TV
