@ Kev
you're telling me that people can't tell the difference of over 300 more pixels, a third better picture? You're having a girraffe. The only time you can;t really tell is if you have a poor source and there's heavy upscalling. they all look the same then, but you wack out planet earth on Bluray on a 1080p 50'', then see it in 720p, downscalled on the same TV, it's glaringly obvious. Maybe you just purchased the wrong telly and are now sour grapes.
And for the record, no-one is broadcasting in full 1080 yet, not even sky, it's all 720 upscalled. And no single provider leased equipment is displaying in 1080p yet, not even available for upscalling, and at almost double required bandwidth for a naive source for progressive, they probably never will.
By the way, don't buy a V+ box, the picture is worse than the classic SD Pace boxes!
