Thanks, Radu.

We recently needed to convert some bags to AVI for one of the
students. I believe we ended up doing a fast-and-dirty screen capture
of some sort. Using bags_to_images and mencoder should work much

If we get the chance, maybe we'll write some generally usable scripts
for this. If someone else does it first, please let us know. :-)
