Ok i was watching you show and was interested in idea for watching things on the pc on a standad tv, but it seemed i lot of work so here is how i have mine set up
buy a Xbox Wireless Adapter MN-740 and hook it up to your chipped xbox running xbmc
now i can take the xbox to any room and stream from the pc (This even works when i take the xbox to my friends (accross the street)
its simple (even my wife can use it), cheap and portable so you can even use in them long summer days when have a few beers and a BBQ with your mates in the garden
