Many people use the cable remotes as the default remote because of the cable features that are available only on that remote control.
I just purchased an LN46A540, and when I get my new cable box from Cox it will be a Scientific Atlanta Explorer 8300HD. I want to know if I will be able to use the TV's remote (which seems to be very nice) to drive that cable box. The instructions give a procedure for memorizing the cable channels which I've done but I must use the Cox remote (SciAtl 2200 for now) to change channels. The Cox remote I have now will turn my TV on and off and change the volume and that's about it; maybe the 8300HD remote is better.
