You'll most likely hook your cable box up to MCE. If you don't have a cable
box (set-top box or STB), then you simply need to go to Radio Shack an pick
up a cable TV splitter.
You can still watch TV in the other room where the extender is hooked up,
but the extender will allow you to watch pre-recorded TV shows from the MCE
You'll need to have the computer turned on to watch anything on the extender
(live tv, recorded tv, internet radio, photos, etc.), but not to watch cable
if it's still connected to the TV.
Keep in mind that you'll want to have either a wired Ethernet cable or an
802.11G or 802.11A wireless network connector on the extender (so it can
access the Media Center PC across the network).
Make sure the tuner card you buy is on the list of MCE tuners:
This is a very different world, but it's worth getting into. Hope this
