Slow/Choppy Playback

I just got my aTV Flash working on my 1st generation AppleTV.  I have my AppleTV hardwired via ethernet to my network and can stream from my NAS drive.  The only issue I have at the moment is slow load times (I have several hundred movies) and when I do select my movie to play, the playback is choppy and pauses alot.  Does anyone have any ideas on how to resolve these issues?


Thank you

I’m having jerky playback on a gigabit Ethernet network with a .mkv file. I haven’t been able to find a solution.
