Just got back from a friend's house. Has been trying for months to get me over to fix up his system. A VCR/DVD combo with satellite, TV and A/V receiver among other things. He tried everything but couldn't get things to work.
Turns out, the combo machine, a JVC, only has inputs on the front. The back has outputs, a combo RCA connection for both sides, a digital audio and S-Video for the DVD and an RCA/S-Video for the DVD side. He wanted to be able to record from the satellite which I could only accomplish by connecting at the front. Why they didn't put an input in the back???
Anyway, he is happy with the result, he's got all systems go. The beer was good too!!!
