The only differences bewtween XP and MCE:
MCE2005 is XP SP2 with a shell extension to run the GUI for your media.
You can obtian MCE specific drivers for your graphics cards and TV tuner cards which will have better resolution (and advanced timing) support for outputting to quality TV's. (unfortuantly these drivers are normally one step behind the latest avaliable).
With the extra .dll's required for the shell extension there is better support to use you MCE remote for 3rd party apps (WinDVD, Winamp, etc).
Personnaly I would stick with a standard XP SP2, download some freeware program which will give you your good looking GUI, purchase an X10 remote to use with, get the letest drivers for your GPU and tuner card.
The vey bad thing I've found using MCE is that all media needs to work through MP10 (which is crappy for codec support, crappy for MP3 tagging and dog slow through browsing).
