If I play the clip in mplayer or with standard decoder in MythTV there  
are no blocking issues.

If I play the same clip with VDPAU as the players walk across the  
court you get a shot quite close of the two tennis players, as they  
walk there is a lot of macro blocking.

This is the sort of problem we are seeing quite a lot on TV One and TV  
2 in particular which are our main 720p channels.
