Please helpme. I am trying to hook up an old tv to a dvd player & a vcr with a littler converter box or an a/b switch type object. how do I do it. I can hook up the vcr or the dvd player but not both at the same time.
If you're using an RF modulator, you should only use one if the TV has no line inputs, connect coax from the VCR to the modulator and RCAs from the DVD to the modulator. If the TV has line inputs, connect the DVD to them.
