I just noticed that using

mplayer ‐af volnorm ‐zoom ‐xy 1280 ‐vf pp=md,screenshot ‐vo fbdev2 dvb://

needs slightly less CPU. Is there a difference to scale=1280:‐2?
Apart from that one problem remains:
When the movie shows a camera sweep (i.e. there is a lot of difference between
successiv frames, e.g. camera rotates around in a room) I  get  some  kind  of
edges  (one  or  two) in the output, like some part of frame n is displayed in
the upper region and the lower region shows already frame n+1 or n+2. Is there
anything  I  can  do  against  that?  (I  tried  ‐double and ‐cache but got no
improvement).

Thanks for all Your help and hints
