Jerky picture with fast movment.

Hi all
I have a realy anoying problem with my ultimo
The problem is when viewing channels its like skipping frames on all channels.
sd/hd making it realy jerky. scroling textg on news etc is ok.
i dont know whats causing it but somethings like cartoons/sport look very interlaced on fast movment.
I have tryied everything to cure it with the plugins and it makes no difrance.

The problem is hard to explain. and all images are the same.
auto res plugin has no effect on it..
anyone got this problem or is it just me?

yea have have tested all.
have also tested with the auto rez plugin set to sd native 567i for sd
it seams to only be some channels and whats being broadcast at the time.

its verry anoying.... Hope its not a hardware problem as its been weeks since i got the box. and its imported. have been testing...
