This directory contains MPEG video bitstreams.  Most of the movies
were created by the Xing software encoder that only produces I-frame
movies.  However, some were produced by encoders that produce MPEG 
bitstreams with P- and B-frames.  At least the following have the
interframes:

	bicycle.mpg
	bus.mpg
	flower.mpg
	mobile.mpg
	sony.shar.Z

We are interested in acquiring more bitstreams with interframes.  Please
contact us if you are willing to donate them to this archive.
