I have been watching a fast-moving video that I'd really love to dissect in slow motion (half or quarter speed; frame-by-frame isn't necessary in this case). Is there a quick and easy way to accomplish this?

You need to join the YouTube HTML 5 beta program and have a compatible browser.

The playback options are as follows

2x, 1.5, Normal, 1/2, 1/4

Make sure to inspect all restrictions as not all YouTube videos can be played via HTML5.

Lovely. I like it! – Andrew Mar 2 '11 at 3:02

First download the video.
Then watch it with VLC and use the slow motion feature.

I don't think it is possible unless you download the entire video on your machine. YouTube's Flash Player does not have such an option.
