vdr -a "cat > /dev/null"

should not do any ac3 decoding, right?
I tried that, but with no effect. And I forgot to mention it in my 
initial post but on the lower end of the image you can see a part out of 
the center of the image.
Can the css decoding be the problem? How CPU intensive ist that?
According to top the CPU ist 0% idle (80% vdr 20% system)
And why do we have to decode AC3 into PCM? shouldn't DVD's contain PCM 
audio?
BTW Andreas: I followed your instructions on how to setup libdvdread and 
  it improved performance. The pauses are shorter now.
