It was the discussion in the "HBO" thread that got me thinking about doing a comparison piece. I might even have done some of the differences you highlighted. In doing more research, I realised that the 2006 Fullscreen DVD was the last ever.
I agree it is a shame that the GOUT was never available as Fullscreen but as the comments above show, even the 2004 Fullscreen seems to have slipped under the radar....
