I have a Wii downstairs connected to my 50" Pioneer Elite. What type of media server or any other type of thing might you suggest so I can stream video to my tv from my PC?
Are you asking just about software? Xbmc or Boxee are worth considering. Can’t you use the Wii with Orb and Opera? If you want to build something check this link: http://lifehacker.com/5406563/build-a-cheap-but-powerful-boxee-media-center
I wouldn’t use the Wii, because it will never play HD stuff.
