Advertisements Comcast updated our channel line up over 3 weeks ago and Tivo has still not updated the channels. They said they had multiple people call on the day it happened. I even emailed them the new channel guide 9 days ago. AND THEY STILL HAVE NOT FIXED IT. All the HD channels are wrong. I am a huge Tivo fan, but this is plain aweful. How hard can this be? Without the right channel line up this thing is useless.
