Thanks everyone, have downloaded and tried some of the files and i am stunned. I have read about how good it is, but to see it for real makes it hit home.
My Media centre is not attached to the net (fed up with the risk of viruses and antivirus software clogging up my system) so I can not try the microsoft demos or risk buying the dvds. This DRM stuff is putting me off buying media. Microsoft should be made to stick where the sun does'nt shine.

I want HDTV !!
