Windows Media Centre in Mac OS

Having converted my household to Mac over the last couple of years, the only bit of PC envy I have is my friends Windows Media Centre set-up he has, where he can record programs from cable in a fully integrated media set-up. I've looked at EyeTV etc and not been impressed so would like to run Windows Media Center on my mac-mini, I guess via bootcamp or parallels. If I buy the appropriate version of Win7, load it onto my Mac Mini, will I be able to use Windows Media center, and what sort of media card will I need to bring in the cable feed?

Cheers
Mark
