The best option would be the HDMI-to-HDMI connection between your player and your TV. But because you mentioned that your TV is an old model, probably it does not have an HDMI port, in which case you have to use the RCA A/V connection. I understand you do not have a remote control for your TV, but you do not program a TV channel to watch DVD movies; you just switch between your TV and the DVD player as your audio/video sources. Here is what you have to do: check on your TV box for a button labeled 'Source' or 'Input'. Press on the button and it will alternate between TV and DVD (assuming you do not have any other device hooked up to your TV).
