No I have not tried wiring up the xbox.  I wouldn't have thought that the streaming/internet access would take up that much bandwidth.  In any case, the mess of cables behind my A/V rack is putting me off from doing it..  Although it would be interesting to see someone else from the forums try it and report back here! 

The xbox is basically my tv/Netflix machine now as I have hardly any time for gaming so far it's technically impossible to stream a game onto my laptop while the wife is on Netflix.  The researchers at Microsoft need to work harder to fix that!
