Can someone help??? I have just purchased a HDPVR and would like some advice on the routing. The cable company says I must split the cable from the wall 3 times. 1) from the wall to HDTV 2) from the wall to the HDPVR 3) from the wall to the VCR I don't have PiP so I'm not sure why I would need the 1st split?!? Second, I have a PureAV power cleaner and would like to know if I should clean the cable signal from the wall before entering the HDPVR or from the HDPVR to the TV?
