My neighbor an elderly woman is addicted to her circa 2002 Sony TV (HD capable) because of its Pic in Pic capability. That can only happen through the VHF/UHF in. It puts like 8 little channels on the screen. Obviously now that cable has digitized everything comes in on channel 3 and no more pic in a pic. She is destitute. Does anyone know if a device is made that can take digital cable channels and convert then 1 to 1 back to VHF ? She has the money for a device like this. ie Cable channel 6 is mapped to VHF channel 6....I am sure it is impossible but I thought I would ask.
About the only way you can accomplish that would be, as MrBobb suggested, 8 STBs and a couple of 4-channel moodulators (or 3 3-channel ones). For everything, though, you're looking at a price tag of $600 or so. Not to mention the headache of 8 converter boxes.
