I have the 160 GB Apple TV which we are really enjoying for not only HD movies but the podcasts and viewing the seasons of my favorite tv shows. I have noticed that when I playback either movies or tv shows that I have used Handbrake to rip from DVD that usually sometime in the middle it has a freeze for a second and then starts playing again. While it is not all that distracting I am always waiting for it to happen when I watch. I do not have any idea why this is happening and have not heard it from anyone else. If I was to upgrade to a 5400 RPM drive do you think that would go away? Also, if I did upgrade it I would probably purchase a 320 GB from Ebay and hopefully install it myself as I have seen the video and think I could do it. Any advice on that account? Thank you.
