Is this normal behavior? I have all my TV shows and movies synched to my ATV. If I watch an episode of Weeds, for example, most of the time the video will hang for 10 - 15 seconds during the first 30 seconds of playback. When it recovers, it will sometimes have skipped over a few seconds of the video. If I rewind, the whole thing will playback smoothly... I have also noticed that my ATV navigation menu will be unresponsive for several seconds in random places (drilling down into My Movies or trying to enter YouTube search criteria, etc.). This seems to occur randomly. Is all of this par for the course?
