My wife hates the cable box we have from comcast (hates the looks). She will not allow one in the bedroom with our new Samsung 3240H. However, I want a cable box for the HD channels, and I believe the tuner might be better with the box. Does Comcast have any digital boxes that have the RF remote, so I can hide it behind the TV stand and still use it?

Doubtful - I think you have to buy your own RF remote and and program the associated transmitter to control the cable box.

Take a look at this for an explanation --> http://www.audioholics.com/news/editorials/rf-remote-controls-is-it-time-for-you-to-step-up

There's hardware for converting IR remotes/receivers to RF, concealing a cable DVR, for example. Just takes a bit of Googling, unless someone has links on hand. Adequate DVR/etc. ventilation is important. -- John
