I wonder if it has anything to do with this code:

    if (asf->dvr_last_vid_pts > 0.0)
      dp->pts=asf->dvr_last_vid_pts+asf->avg_vid_frame_time;
    asf->dvr_last_vid_pts = dp->pts;

Isn't dp->pts wrong?  After a seek, dvr_last_vid_pts is reset to 0.  This
code sets dvr_last_vid_pts based on dp->pts (which was wrong)g.  The next
frame's pts will be based on this wrong dvr_last_vid_pts value plus the
estimate of average frame time.
