Hm, you are right. The danish_dvb is still not fixed completely. My PTS dump
shows that there are fluctuations in frametime, for some reason there are
bursts when frames get played at double speed, then playback slows back down
and corrects. This is due to blit frames not being homogeneous. Sometimes
there are no "frames" without image (i.e. first fields where blit=0), but
blit=1 sequences come.

What is the logic behind correct_pts dropping blit=0 frames? I still don't
understand it...

The true fix would be to not split interlaced double-fields into separate
frames...
