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?
