I just committed the bugfix to CVS. The bug was that the display functions of 
playdv (dv_display_cleanup) were being called twice.

That should not be the case since the bug was clearly isolated to playdv, and 
I never saw it while using Kino. I guess I rarely let playdv play to the end 
when I use it, which is also a rare occasstion. What gives you the impression 
apps linked to libdv are affected by this?
Thank you for the bug report.
