When it comes to an RCA brand television set, connecting a DVD player is no different than with any other TV. Your older, tube-based model should have the simplest connection ports needed. The newer hi-definition models cane give you multiple connection options for better quality. If you have just a simple DVD player, your connection should be separate from any cable or satellite receiver you have with the TV. A DVD recorder should be connected so the cable signal goes through it and then to the TV.
Check all the input ports located in back of the RCA TV. It needs to have at least composite ports, which are the three round sockets colored yellow, white and red. It could also have an HDMI port (it looks like a small, stretched trapezoid) or component ports (similar to composite, but colored blue, green and red).

Disconnect the cable/satellite receiver from the TV only if it is using the TV input port you want to use for the DVD. If this box is connected through an RF coaxial cable (the thick black cable that is twisted into place), you don't need to disconnect it.
Connect the DVD player to the TV using the best cable connection available. an HDMI cable will transmit the bast video/audio combination. If you can't use this, the composite cables (yellow, white, red) will also carry both video and audio. Component cables (blue, green, red) may give you the best video quality, but won't transmit audio.
Connect a cable to the DVD and TV for audio if you connected the video with component cables. The simplest connection will be through composite audio cables. This means you only need a cable that has red and white plugs.
Attach your cable or satellite receiver to the DVD's input if it has one. You should only need to do this if you are using a DVD recorder instead of just a player. If the DVD recorder has an RF coaxial port, use that. Otherwise, link the cable/satellite's output to the DVD's input through composite cables.
Re-connect your cable/satellite receiver to the TV if you had to disconnect it (Step 2) and did not connect it to the DVD's input (Step 5). Using the RF coaxial connection is your best option.
