Getting pretty happy with this. Video & volume scrubbers are both canvas. The code is similar enough for both that I shuold be able to write a generic scrubber handler piece from this. I made them both taller so that the highlighting the adjacent elements is less likely. This also allowed me to trim back on the CSS needed to position everything.

The player/controller also adapts to the size of the video element automatically. Mostly it's just the video scrubber that has to be adjusted to 40% of the player area +8 pixels, or (player.videoWidth*.4)+8. The plus 8 is meant to be a buffer to deal with the fact that right now you have to scroll out of the scrubber to hit 100% duration or volume, but I have not wrapped that up yet.

Pretty happy to have taken this so far w/o any real dependencies, no jQuery, prototype, etc. Firefox is proving to be a cunt of a browser right now, but will get her tamed a bit next time around. The code for fullscreen was just kinda thrown together at the last minute, but will address that as well.
