Just did a screen-grab of what to expect. You can't (unfortunately) full screen the game, but it's still of a good enough size to watch on a small laptop screen. Plugging your laptop into a large screen tv should still give you sufficient viewing of the match along with match stats and current odds at the side.
I'm sure there's ways around lifting a flash player and making it full screen though. Alternatively, there's probably going to be firstrowsports streams or something using the footage off the betting site.
I didn't have to bet either. Lodged a tenner into the account there and without having to bet I was able to watch a stream of Stuttgart v Bremen.
