Hi. Hopefully someone can help me help a friend. He moved an old DVD player to his bed room and has it connected to an old TV that only has the coaxial cable input. He has it running through a VCR in order to connect it, but this of course activates the macrovision. I know they make an adapter for the RCA cable to coaxial (and I told him I'd figure out what he needs to get), but I'm having trouble finding it. I did a search on Radio Shack's website and had no luck so far. Anyone here know Radio Shack's part number for this adapter?
