I had the blanking too and the crowd noise disappeared for a while. I also noticed that the whole game was in DD 2.0 and not DD 5.1 as it was on friday.
The quality was still much better than SD though - the artifacts surrounding players were not visible on HD and the grass and crowd were no where near as sharp on SD. The colours were also still more vibrant. I guess there will be a wide range of levels to the HD quality depending upon bitrate - I gather BBC is 17-20mb approx and HD-DVD is 37-50+ average!! The base should always be better than SD but closer to upscaled SD (which we have on the TVDrive).
Not sure I saw a big difference between ITV and BBC though - swings and roundabouts - it was all good in general. This sort of HD isn't wow but it raises the bar significantly.
Having said all this does anyone feel that all we actually doing here is bringing digital TV up to the level of good old analogue terrestrial PAL broadcasts as they were 10 years ago? Those were the days when artifacts and pixellation were none existent
