Yeah. I get a lot more channels over the air. Neither NBC-HD nor
CBS-HD are available via my cable company at all. Also, it is a known
fact that most cable companies (mine included) reduce the bit-rate so
they can cram more channels in.
Only reason I am doing this, is I can actually get TNT-HD in the
clear. There is also a small hope that they may start sending ESPN-HD
in the clear.

That is what I am afraid of.

Yes. Tried a high-quality (low noise) 15db amp at the point the cable
comes into my house. Made no difference.
I actually have to use a signal attenuator to get a good picture from
my PVR-500, so I tried using that on the HD-3000. Made no difference.

Hopefully someone on this list has good QAM reception with something....

I really wish someone would come out with a commercial box that has a
"cable card" slot, and firewire output. Not going to happen, but I
can dream.
