I have AXEL GeForce 440 MX (maybe also -SE) DDR 64MB, i can play
files up to 1920x1088 files without visible artifacts.
I belive that this is hardware problem. But it is known that on
weak cards some optimizations should be removed to get
more stable picture (e.g. increase latecy etc.).
That's the reason all manifacturers to make their own drivers, despire the
nvidia one.

it. :(
