Although it may seem confusing, connecting a DVD player to a cable TV is relatively simple. Whether you have a cable box or not, you can still connect a DVD player to your television. If you understand the principles behind A/V electronics, you can connect a DVD player to any setup.
Check how your cables are set up. If you have your coaxial cable connected directly to your TV, there's not much to do. Connect the DVD player to your TV using the applicable cable. Examples include A/V, S-video and HDMI. Make sure you plug the cable into the "video out" connection on your DVD player and the "video in" connection on your TV.
Check the back of your TV for A/V-in connections. If you have two sets of connections, you can use one for your cable box and the other for your DVD player. If this is the case, follow the directions in Step 1 to connect your DVD player.
Get an extra coaxial cable if you have a cable box and only have one set of A/V in connections on your TV. Unplug the cable from your TV and plug it into the "TV in" connection on the DVD player. Get the extra coaxial cable and connect it to the "TV out" connection on your DVD player, then connect the other end to your TV. Once this is finished, you'll have the cable from the wall going into your cable box, another cable going from your cable box to your DVD player and a final cable going from your DVD player to your TV.
After you finish Step 3, use the appropriate A/V cables to connect your DVD player to your TV as detailed in Step 1. Remember to connect the cables to the "out" connection on your DVD player and the "in" connection on your TV.
