In case someone is going to work on this, I mention that
there is some code here

http://java.sun.com/products/java-media/jmf/2.1.1/solutions/J
pegImagesToMovie.html

that will convert a collection of JPEG images to a movie to
.avi or quicktime using JMF. I'm guessing that starting from
this it would very quickly be possible to get the same
functionality as offered by visad.data.qt.QTForm

I also have some suggestions for a more sophisticated
playback module. In the past I have used keyframe animation
systems in order to generate movies where individual frames
could not be generated in real time. I think that if such a
system were to be implemented well for VisAD then this is
potentially "killer" functionality that would draw users and
developers like a honeypot.

Regret I have neither the competence nor time to build this
myself but I can provide info on how it has been done in
other systems and I will also volunteer to so some user
testing.

Perhaps the best key frame animation system I have seen was
inside AVS: why not reverse engineer this approach? 
I can probably find some documentation on this if that would
help.
