Had to fix JMF_Movie_Analyzer since for some reason (perhaps related to using
uncompressed video) it was not getting the right duration, and therefore not
the right number of frames.  So rather than using a for loop from 0 to totalFrames,
there is now a while loop that goes as long as the new frame number is higher than
the last one.

Also disabled the saving of each frame as for large video files this eats up
too much memory.
