No filters on individual channels either. How can i track down why the picture 
is moved down a bit? And why 540 and not 576 as fullscreen would be? Because 
the blurrieness of my recordings just seems as if there aint not all lines 
drawn correctly, and not with 2 fields. Whereas in the frontend everything is 
crystalclear. Iīll try to reinstall the nvidiadrivers.
