I just registered myself on this forum so that I could say THANK YOU for the previous posts from Kubakai (on 03-13-2007), Superhooper (on 08-03-2009) and Motorbaby (on 05-11-2010). My remote quit working about a 45 minutes ago while watching Grey's Anatomy. Husband tried for a half hour to reprogram it using documentation from Comcast. He gave up and said we should call Comcast...but we all know that means ALOT of frustration. So I googled 'program Comcast remote to cable box' and lo and behold, this forum popped up. It took me a couple of tries (had to use the leading zero), but it worked! A BIG THANK YOU!
