It does.
But do you see the potential nightmare for all my senior customers that
still have an issue with "... OK the box puts out on chan. 3, but I
want to record with my VCR a chan. 13 movie, but I don't set the VCR to
13? Why?.. I want 13...I get a blue screen...And how do I get sound
again with the surround amp on VCR but not cable?"
Oh, God. I'll need a full time instructor to man the phone.
