I have a couple of questions regarding MCE, and thought it might benefit from
explaining my current setup.

I have a Sky STB, connected to Tivo in the living room. Viewed via a DMTECH
26" LCD. This setup will remain unchanged, and is my primary point to watch
TV. I don't use the sky remote at all, using the Tivo remote and a Tivo IR
Blaster to change the channel on the STB. Works perfectly fine, very please
with it.

In the bedroom I'll have my MCE PC and monitor. The room is currently
getting refurbed, and it's my intention to route av cable and my ethernet
connections away under the floor to elliminate as far as possible the wires.
I want to contuinue using Tivo in the main room to watch TV, but in the
bedroom I'd like to be able, when desired to change the channel on the STB
using the MCE remote and extender. This is most probably at night when no-one
is watching TV in the living room. My initial thoughts were that I therefore
needed to run the IR cable all the way through into the living room and
attach to the STB. Is this correct? If so, will this not impair the operation
of the STB while using Tivo as I'll have to stick the end over the IR
reciever on the STB.

Sorry to be so long, but the more I think about it the more I come to the
conclusion that the MCE and STB need to be in the same room? Say it aint so?
