Is anyone else having major problems with the Apple TV 2 losing its connection to iTunes. Basically, I open iTunes, and it shows up and everything works fine on the Apple TV. Then, after some time after turning the Apple TV off (and I leave iTunes open almost all the time), and turn the Apple TV back on later in the day, my iTunes is shown but when trying to access anything all I get is the white spinning wheel. I have to close iTunes and reopen it to reset the connection. This has been happening for a while. Anyone else have this problem?
