There's a few of other changes.
When I press the Home remote button, the screen is 720p50, never knew that. And as I don't know of any other source of 720p50 (BBC iPlayer always seems to be 720p25 and the YouTube 720p videos I've looked at were also 720p25) I don't think that there is a reason to select a setting of 720p.
The switch between resolutions isn't seemless, so going between 576i and 1080i results in a whiteish screen for a second.
SD (576i) seems worse when upscaled to 1080p by my Panny plasma compared with the V6, quite surprised at that. It just goes to show that you need to do some experimenting to find what your equipment is good at.
