Hello, I just started watching Desperate Housewives S3 through AppleTV, and it stopped through the episode. The timer kept going but the audio and video has stopped. I checked it with a few other episodes and the same thing happened. Some work and some don't. I backed them up to CD with iTunes back-up, and have recently added them back to my computer because of Atv... but the files are corrupt (i think) Can anything be done?
