I just got Radio Shack's new RF modulator and I have to say, what a great piece of equipment. Not only could I run my DVD to it the out to the TV, but it has an ANT IN coax so I can run my VCR into that then out to the TV. When the DVD is off, no signal comes through, so I can watch regular TV or VCR. Then if I want to watch a DVD, I just power it up and it bypasses the VCR automatically and plays, and here's the best part, WITH NO DISTORTION OR PICTURE NOISE. $30 vs. $300 + for a new TV. I love it!
