hi there. I know this doesn't address your question, but I wanted to say that even though the comcast guys paired my comcast remote to my samsung lcd tv for me, that remote was still pretty bad... and what's more, reaching among three remotes (tv [because the comcast thing didn't take care of all cable box features], cable box, and sound system) was a headache. I bought one of the logitech harmony universal remotes... model 520... and after I spent the time with my computer customizing the functions for the three things, it has been a dream. so I would just say don't waste your energy trying to get comcast's remote to work, instead get a good "activity oriented" remote like the harmony ones and invest your time in that. a serious, serious improvement.
What procedure would I need to go through in order to get my Samsung LN19A330 to pair with my Comcast remote control? I've tried Comcast's suggestion for automatic programming (http://www.comcast.com/MediaLibrary/1/2/CM/VanityURL/documents/comcast_on_demand_remote_manual.pdf) and I even tried using all the Samsung TV codes manually. Is there something I'm doing wrong?
