Are you sure you need to upgrade the OS, or just do all the software updates that MS sends down? The reason I ask is this: I have a 2002 Media Center PC that I have upgraded to Service Pack 2, and I have downloaded all updates that MS notifies me of.
Like said above, there is really no reason to update your OS to MCE 2005 if you've been updating your current version of MCE.
I'm running MCE 2002 and my understanding is it's the exact same thing as MCE 2005. I can connect to my 360 just fine.
