The Apple TV 2.0 ("Take Two") update has been out for a few days now to generally positive feedback. Unfortunately, according to MacFixIt, a number of users have cited problems either installing the update or have reported issues with the update once it has been installed:

"When I download the software update "take 2" my Apple Tv restart very quickly and return to the 1.1 software. I can't update to the new software." "Everytime I go to update my Apple TV, it downloads the update ( about 30 minutes), then as I apply the update, it goes to the Apple logo and then back to the menu saying that the update failed. I've repeated this several times to no avail." "I am unable to apply upgrade my original Apple TV. The upgrade stalls and quits. Unplugging the Apple TV and even restoring original Apple TV factory settings are to no avail!"

Other issues reported with the update include the units brightness settings menu as missing after the update, some HDMI users reporting that audio no longer working through HDMI after the update (switching to component cables solves the problem) and TV shows purchased from the iTunes Store not playing, the Apple TV telling the user the shows are in an incorrect format.

Still other users have reported problems syncing to their iTunes libraries. Interestingly enough, several users reported that fixing permissions via the Disk Utility application resolved this problem.
