I know what you mean!!!
I've tried every setting possible on my Sony 32" LCD with no luck, you mean when the camera moves with the flow of the game the pitch turns blurry,as tho the tv cant handle so much green.
I think its all down to the quality of the broadcasting, if you take a look at the spanish footy tonight, thats even worse including blurry shirts.
And i agree Eurosports transmission of the African cup are only just watchable,think they filming them on a mobile phone lol
