I was thinking about this earlier this morning and I remembered that you said DVD player (not a player/recorder). A simple way to hookup a DVD player is to take the three pronged wire with the white-red-and-yellow connectors and plug one end into the back on the DVD player (matching the colors of course) and to plug the other end into the back of the TV. The newer TVs come with an Input selector on the remote under the label Input. Some TVs tell you which Input you are plugged into on the back of the set or you can look at the manual to find out which Input the three pronged wire went into. The coax cable is always Input 1. Turn on the TV and put a DVD in the DVD player to get it running. Take the remote and press the Input button until you get the DVD screen to come up. From then on, go to Input 1 to use the TV with the Comcast box and go to the other Input to use the DVD player.

If you use an entertainment console, look at the manual to find out where to plug the three pronged cable and what button to select on the Entertainment console remote to get it to select.

Hope one of these solutions helps.
