The best way to connect this without any signal loss would be to use firewire out of your set top box (if it has it) and if your DVD recorder has it as well. I am not sure if the DVD/VCR recorder from Panasonic has this. The other way is to hook it up with s-video and composite audio. So, take a good quality s-vid from the ATSC tuner and go to the DVD recorder s-vid input and you should be fine.
