The upscales non-HD channels as it outputs a master resolution of 720p, so anything non 720p neds to be up (or down, tho nothing is broadcast in the UK higher than 720p yet) to fit the resolution. This shows some improvement, but not a whole lot. What it does do is reduce the ammount the TV needs to upscale, as the TV is being fed a 720p res constantly.
