In my continued quest to get my Apple TV working, I'm now looking at my Drobo as being a possible weak link. I'm having problems with stuttering video and that would appear to be caused by the ATV struggling to cache the video across the network. I've now patched the iMac and ATV in to the same AEBS and am still having the problem at times. The only other thing I can think about is the fact that the Drobo is connected externally via FW800. Could this be the bottleneck? Just wondering if anyone else has got this setup running and could comment? Thanks!
