Brian,

Thanks for your reply.

I don't have a TV connected to that specific cable, but I have a 
fully-functional signal coming out of a common splitter that goes into a 
XP box with a WinTV PVR-150 card.

As far as HRC and IRC are concerned, I don't understand.  I'm not using 
a cable box - it is just a straight cable from the outside (it is not a 
signal issue since all is fine on my XP/PVR-150 box that shares a cable 
into a splitter).

Steve
