And so, today I installed FFDshow, and now it seems I have every codec 
under the Sun! o_O

I used to use Huffyuv to compress my POV-Ray videos. As I remember it, 
this used to make them ~20% to ~80% smaller. Well anyway, I just tried 
that tonight on a video I'm working on, and it shrank the video down to 
1/10th of its original size.

(OTOH, the video is actually rendered at 1/4 resolution and then scaled 
up, so most of the pixels are actually the same colour.)

But then I tried some codec called "FFV1", and the video shrank to 
1/100th of its original size! o_O

Weird thing: If I play a video compressed with Huffyuv or FFV1 in WMP, 
the black background comes out dark gray, and there seems to be slightly 
ghosting to the edges of the pixels. But if I load the video into 
Virtual Dub and decompress it, and play the decompressed version in WMP, 
it looks crispy-clear. Like, WTF?

Anyway, once I have some full-resolution videos, I might try playing 
with lossy codecs. Until then... does anybody else have any good 
recommendations for *lossless* video codecs?
