Nevertheless, on replaying there are _sometimes_ some distortions
visible (`Kloetzchen') and audio sometimes gives sharp noise.
Whereas if tosvcd uses marks.vdr to do a svcd image using
mpeg2enc this seems not to happen.  mpeg2enc seems reorder the
PTS and recalculates sync offset of the audio part.
