I have a new Panasonic TH42pd25. After the initial hook-up I've found a problem with the TW DVR box supplying the HD signal. I had my Panasonic DVD-R connected before the HD box connected through my DVD-R then to the TV. I was able to burn DVD's using this set-up. Now, I was instructed to go directly to the TV using composit connection from the cable box. With this arrangement, I can no longer burn a cable signal. Do I lose quality signal, if I go from the HD cable box to the DVD-R and then to the TV? Is this something to do with copy protection? I do have a Panasonic 5.1 receiver, but didn't want to put my video signal through it. Please help. I don't want to lose DVD burning capabilities.
