Loren;

I have the starter kit. It is X-10 compatible.

The kit works fine, and allows you to control lights using the tv screen/DSS remote. I did not find this method at all helpful. You have to stop what you are doing, switch to the menu, switch to home control..etc..etc..etc.

A much better solution is to use a Phillips Pronto remote, and an IR to RF converter (about 30 bucks I think). I have numerous X-10 controlled devices (and the Active Home software), and control via the pronto (including dimming) works great.

Hope this helps, if you are still interesting in the RCA connector let me know, I'll sell you mine.
