Is it a really high frequency? I hear that on any TV broadcast here anyway- at first I had thought it was a product of the CRT itself in the TV, but then I got a TV tuner, a Phoebemicro TVMaster, and it also had that high-pitched sound. I wonder if the VCR is accidentally 'filtering' it out because of less-than top of the line audio hardware?
I don't know what the tone is though, what causes it, or how to get rid of it. That might take a cable TV expert, if this sound is what I'm thinking it is.
