Or what I have done in the past is buy the cheapest Radio Shack model and reprogram the VCR key as a TV key and then make the TV code the same for both the regular TV key and the VCR (now a TV) key. So then the older person can't switch to VCR by mistake.
But when I just looked on the Radio Shack web site I couldn't find that cheap simple remote listed. (It was about $10.)
