After doing some more digging with my TV's tuner and calling Comcast, I
think I have figured out what is going on:

Comcast is encrypting their channels. If the cable is connected
directly to the TV, USA-W is horribly pixalated and there is not sound.
If I connect the little DTA box, the picture and sound are perfect. The
Comcast agent told me that they have been encrypting their channels.

How are people dealing with this issue?

Thanks
