Given that a lot of the forum members are Linux fan-boys we shouldn't forget that some here use Windows, even if they don't want to admit it publicly
One of the guys in the clan I'm in has been having all sorts of problems with getting Vista to talk to his XBox 360. After several "I told you so" posts on our forum from me. I came across "orb" and you know what it's great.
MyCast your digital media with Orb 2.0 remote pc access software
It's one of those "It just works" things. I mean it really dose... Install orb on a Windows PC and register with orb. Then you can stream any media straight from your PC to any Internet enabled device. It figures out what bandwidth is available, how big the screen is that is viewing it and adjusts automatically.
I'm using it to stream movies from my main PC to my laptop(ubuntu). My m8 is doing much the same at home watching movies on his TV through the XBox thingie. Also he is wasting time at work watching movies on his laptop.
