Hi, I have a dvr522 with two televisions one near the receiver and one upstairs. 1) TV1 -- tv connected to vcr. The vcr connected to dvr (all coax ) no rca nor s-vhs. THe vcr is unplugged for testing. It still works. I don't understand how this can be. If the tv is ONLY plugged in to the vcr, and the dvr hooks into the vcr only, why would this work? 2) Wouldn't the better connections be s-vhs (first if available) then rca 3 cables, then coax? 3) Upstairs tv with uhf pro---- no cable connected is this handled strictly by the wireless signal from dvr on a high #'d channel . It's set to cable channel 73. 4) Now with this logic, if I buy a laptop with usb2.0 external tv card. If I'm in the room with tv1, I could hook this to the back of the dvr tv1 with either rca or s-vhs and get same channel as on tv1. If I go into a separate room altogether, and set up the tv card to same channel as on tv2, I should get a wireless signal there as well, although probably same one as on tv2. 5) If one had more than 2 tv's , would the others pick up the same channel as tv2? Much thanks for your comments on this.
