I have a Sega genesis 2 console with the RF, and it works on my daughters 13 inch tube TV (because it has an RF out on it) and my LCD does not so I have tried running a/v cables through a VCR and running it through my TV and the genesis RF through the VCR and got nothing and I cannot get it to work running it through my cable box either. I have a Comcast HD box with DVR and still nothing, the system works great on the older TV but I wish I could play it on the 47 inch flat screen.
