To help with space issues I recently moved my entire tv show library to an external hard drive connected by a usb 2.0 to my airport extreme base station. I then set up itunes to recognize that the tv shows were now on the external drive, and all of this went smoothly. My problem is when I open the show in front row or in itunes it takes a second to load (which I know is normal) then starts playing... pretty soon after though it begins to hiccup and lag and freeze/jerk.. I have read other people with a similar setup and they seem to be having this work fine. My AEBS is set up with the 802.11n Only (5GHz) setting and it's all running on my macbook pro (2.4 GHZ core 2 due, 4gb ram) so my set up should preform this simple stream seamlessly no? maybe I have a setting wrong or something? any ideas??? thanks I was seriously looking into an Apple TV, but if it does this same jerkiness then it would be unwatchable.. thanks for any help!
