Hi,

When I started the project, I didn't know about libmovie. Where can I go for
more information? I am just loading one screen at a time.
I plan on multithreading, but haven't yet. I plan on having one process that
just does glDrawPixels(), and glutSwapBuffers() and 3 process that decompress
the images an put them in main memory.

Thanks,
Doug

So you just read and decompress one image at a time, draw it to the screen
and go on to the next? If so, wouldn't libmovie do just as good a job? I
suppose that what you could do that libmovie can't is to spread image data
across disks, if necessary. Also you might have a separate thread to load
image data before it is actually needed....
