Video Playback

Is anyone experiencing problems with video playback? I'm able to listen to music and view photos without any problems. My home movies play fine. However, my iTunes Store bought tv shows and music videos freeze during playback. This happens with both synced and streamed media.

My video setting is 1080i.

Any ideas?

Problem Solved

Temporarily unplugging the unit forced a reboot and solved all of my video playback problems.
