Well, I received the IRF-6 this morning and wasted no time installing it and modifying my remote to accomodate the RF. I'm controlling 4 different components using RF--Faroudja DVP-2200, Denon DVD-5000, TiVo and DTC-100. All of them worked almost flawlessly at the first try.

One word of advice however, the antenna positioning is VERY touchy. I found moving the antenna only a few feet could totally disable reception. I've got it about 5' off the ground and about 3 feet from my component shelf. I'm somewhat surprised at how critical this seems to be. But, since I've found the "sweet spot", I've had totally reliable control.
