Ok well when using quicktime to play back movies via afp i get hiccups, every couple mins the screen freezes. I then tested the same movie using myplayer with a large buffer,aka cache, and playback has been perfect. Now im glad its working but i hate the mplayer interface, i really want to use the quicktime player. Has anyone figured out how to increase the quicktime cache.

system preferences > quicktime >streaming > set LAN for speed
