I wanted to buld a media center pc, so i just install it (you can get it oem) and get a remote right? Do i NEED a tv card with it and if i do whats HDTV and is it better than freeview? Do you get HDTV freeview or what? Will the tv card work with windows media center 2005 and what is actually different with windows media center, can i use it just like a normal pc for like ofice, internet and games?
