It's great eh? You get to see what it really looks like. Colours are different etc. I only wish I had a widescreen Tv close to the PC. All my previews are squshed up.
Also great for me is that the Matrox drivers have utitlities to preview from within Adobe Encore tothe TV as well. And even an export option in Photoshop tothe Tv screen too
It's the only way to go.
