You're probably not doing anything wrong, it depends on the driver
you're using.  Player drivers don't usually implement all of the
functionality exposed by the interfaces.  It might be the case that the
driver simply doesn't handle changing zoom with a velocity control, and
only takes absolute positions.  If the driver isn't documented, you'll
have to look at the code to be sure.
