Well, I spent a good 2 hours last night trying to get my song library to sync to my new AppleTV. Finally, I discovered that none of my songs had the little box checkmarked. Once I did that, the whole library synched without a hitch. My question is what are those checkmark boxes there for? Apparently all of them should always be checked? Oh, and AppleTV is freakin awesome. They do need to make a more expensive model with a larger hard drive imo.
