This is consistent with what I'm experiencing -- channels 2 is the worst
of all, 3 through 6 are about equally bad, 7 through 13 are a bit better
but still not perfect, and 14 and up is where it starts to get better.

29 was just an example of a channel here that _always_ comes in clearly.

Leaving the TV Tuner card on channel 3, and running the cable TV through
my VCR (using the VCR to choose the channel) doesn't make the lower
channels look nearly as bad. I don't want to leave it setup like this
because the VCR isn't stereo.
