I doubt that this will be available on the xbox. MS control it tightly and they tend to favour the US, so anything for just the UK would be low on their list of priorities. As already said, the xbox doesn't even have a web browser. I think opening it up slightly would stop the tight control they have on Live etc.
Installed the new PS3 update earlier and watched last weeks Survivors. You can kind of get pseudo full screen. You have to have the iplayer control bar at the bottom and some blackbands at the edge. It's also a tad fiddly as you have to zoom and move it using the right stick and then move the pointer out of the way carefully with the left stick. If you're not careful you nudge the picture off centre and have to start again. Quality is ok, no worse than watching Setanta football on NTL!
