I own the 47pfl7403D/f7 tv, onkyo 605 receiver, rca vcr, panasonic 80 bluray player, toshbia bluray, ps3, roku, direct tv HD, and a philips upconversion dvd player. I have 2 meters HDMI cables from from my stuff to the tv and receiver. I have ordered the switcher and hope to get it on tuesday. I also have the harmony 720 remote. Iwas having problems setting it up. do I really need to leave everyone on with I use the switcher? I will have the toshiba, ps3, direct tv, roku, philips dvd player hooked up to the switcher.
