Hi,
Ah thought I'd put that in my original email, but looking back I see I
hadn't.
No this only occurs through the viaslice output driver, playing the mpeg
stream through any other player/machine and the quality is just perfect.
It looks like it is specific to the viaslice output driver. I just wanted to
check if any other CLE266/unichrome users were seeing this too before I
started debugging just in case something was faulty on my machine.

The effect is similar to the macroblocking... but not quite!
