[Debburn-devel] Wodim reduces writing speed for Video DVDs to 4x for no reason

I have a problem with wodim. When burning a Video DVD with K3b as the
frontend and wodim as the backend, wodim reduces the speed to 4x.
In fact my DVD writer is able to write my DVDs with 16x. As far as I
know even with 20x.
My writer is a Pioneer DVR-216D.
The DVDs I'm usually using are Verbatim DVD-R 4.7GB 16X AZO.
It would be nice if this could be fixed.
This is the truncated log:
