How do I connect a combo dvd/vcr to a dish network satellite dvr/tv?

Hi Car54,
Take the cable running from your satellite receiver to your television, disconnect the TV end, and attach it to the input (in from antenna) on your DVD/VCR. Then connect the audio/video ouput of your DVD/VCR to your TV using the desired cable(s) of choice (Coaxial, S-video, RCA, RGB). And your done.
Your Dish Network service will probably be broadcast on TV channel 60(?) or some such, so in order to watch your DVD/VCR, you will have to change the TV to channel 3 (4 in some rare cases). When done, switch your TV back to the satellite broadcast station to view your satellite service.
Hope this helps. Take care. :)
