No, I've never seen any device that would allow you to output from a VCR or converter box on any other channels except three or four.
Is there a device, multiplexer or something that would let me broadcast my device, say VCR, DVD player, computer, etc. onto a free channel with to other video on my cable tv? So I could just tune into say channel 66 for my VCR and 71 for my DVD player and so on?
Thanks for your help.
