TV/VCR Set-up Using Coax:
The input cable will be a CAT-5 coming from jack on the wall into the set-top box. From the set-top box there will be a black coax cable going to your VCR IN connections, from the VCR OUT connection there will be another coax cable going to the TV.
DVD's always hook up using what is called video and audio. You will need to have video and audio auxilary inputs on your TV or have what is called an RF modulator which takes the video and audio and changes to an RF signal, usually channel 3 or 4. The video lead will be yellow, the red lead is right audio, and white is left audio. There is also S-video cords, which is one of the best video sources. This is a special cable and your TV will need this type of input on the back to use this cord. In this case you will have a red connector which is the right audio and white for the left audio.
The TV will need to be set on the video input to watch the DVD, some TV's have multiple video inputs. You will need to know which video input that your DVD goes into on the back of your TV. To change inputs on your TV, press the input or source button located on your TV remote.
There are many options and styles of audio receivers. Please consult your owner's manual for set-up instructions.
