Comcast cable sucks. Their equipment is on par with old 8track tapes. I just recently changed to Direct TV and have state of the art and my HD picture rocks and 5.1 sound is awsome. I ask myself, why didn't I do this sooner? It has been a month and comcast has yet to refund my $86 credit on my last bill, and gives me the run around when I ask about it. They have been sucking , suck now, and will continue to suck in the future.
