If you are setting up a DVD player, you have the option to use an alternate connection method, such as RCA or component video, to connect it to your DTV converter box and television. This is because a DVD player has no receiver, so it does not need a coaxial connection to provide radio frequency signal. Also, you may experience overall improved picture quality when using component video rather than RCA (also called composite) or coaxial to connect your equipment. Use the RCA or component video cable to connect the DTV converter box to the DVD player's input ports if it has them, and then connect the RCA or component video outputs on the DVD player to the input on the television. Use the "Input" or "Source" button on the DVD player or DVR remote to switch between DVD playback and DTV input. You can also use RCA cables to set up both a DVD player and a VCR to your television, since most TVs and DTV converters have only one coaxial port. To achieve this setup, simply use coaxial cables to connect the VCR to the television, but use RCA cables to set up the DVD player. If the right ports are available, you can also use RCA or component video cables to connect your DTV converter, VCR or DVD player to your television.
These tips should help you to connect your DTV converter box with a VCR, DVD player or DVR. If you have trouble, consult the documentation for your home theater equipment.
