Been having an issue where some movies will not play on my ATV2. After I select a movie to play on my home theater setup, the wheel will spin (or tick) endlessly - will not come back with an error. They play fine on the computer - iMac / iTunes - just won't stream to the ATV2. If I Fast Forward the ATV2, I see a frozen screen shot of the proper spot in the movie - but the movie will not stream. Last night I tried about 6 different movies - none would play. After checking for software updates (none needed) - rebooting the ATV2, rebooting the iMAC, resetting the wireless config in the ATV2 - some movies that did not play earlier would now play, but not all of them. I download Apple format movies or use Handbrake to convert them to ATV2 format. Any thoughts?
