And if you never read the scratch frame's frame number, it doesn't
have a chance to screw anything else up.  I made a patch based on your
advice and entered it in Trac (Ticket #1151), but as it turns out, it
doesn't fix the problem.  I still get the unpredictable jumping back
to zero while skipping forward.  Did I misunderstand what you were
suggesting?
