Phexx: Awesome have you, or other used WMC? Do you recommend using it over included software?
To be clear, by WMC you mean Windows MediaCenter right?
If so; then yes. Lots of people here use it. I think the general consensus would be that if you are installing/running Windows 7 and getting into a media centre for the first time then try Windows MediaCenter first. If you find that doesn't suit you, for whatever reason, then try something else.
Windows MediaCenter really is a doddle to set up and use. Its also extremely non tech person friendly. And thats the reason we use it at home. Plus it looks nice too (which is an important wife acceptance factor - never underestimate this!)
