Scientific explorer 8300hd problems

So I have the My book AV hooked up to cablevisions Scientific atlanta exploerer 8300 hd. I continuely get pixalations and freezing all threw my recordings. Especially happens when i am watching a sporting event and typing sometine else. When taping 2 shoes we continually get pixalation and sound distoration. I am connected to the cable box by a esata connection. I tried looking on this site to see if there was a firmware fix. Any advice?

cbear55; this is the forum for the WD TV Live media players, not the MyBook AV.

very sorry i will repaste
