What? Using VCR's to distribute signals? That would cost even more than 2 channels of modulation. That's not a solution, it's just more of a problem. Now you're adding way more equipment. VCR's can still only output on channel 3 or 4. Why not set one Sat receiver's output to channel 3, and the other to channel 4? Combine the 2 outputs then distribute them. Use sat receivers with UHF remotes and set them to seperate codes. Problem solved?
