A number of iTunes users are reporting difficulty playing back purchased TV episodes in iTunes following the installation of version 9.2. Similar to a problem that surfaced with iTunes Movie Rentals shortly after their introduction in January 2008, affected users are reporting that after downloading and attempting to play a TV episode using iTunes 9.2, iTunes repeatedly asks for authorization despite the fact that it is already authorized, and eventually plays the video, but only presents a gray screen with no sound.
Interestingly, these same TV episodes appear to playback normally on other authorized Apple devices, suggesting the problem lies within the iTunes installation and not the file. Apple has yet to acknowledge the issue.
