I know it must be very easy to do, but a friend of mine just called me and he can't figure it out. I don't even have a vcr set up at home, so I figured I'd ask here to make sure I get it right. I assume you just use rca cords and go from vcr 1 audio and video OUT to vcr 2 audio video IN and then play the tapes in vcr 1 while recording in vcr 2 but I wanted to make sure that that's right. Does it make a difference if a coax cable (cable tv)is being run through the first vcr? Does a coax line need to go to the 2nd line?
