So... I see the video sorta plays on my otoro device... I hear the sound playing with occasional audio under-run, and there's plenty of video frames dropped.

The <video> element on that page has markup:

        <video id="v"
               width="160"
               controls
               onloadeddata="e('v').currentTime=15; e('v').volume=0.1;">
          <source src="http://pearce.org.nz/video/quake-720p.webm" type="video/webm">
          <source src="http://pearce.org.nz/video/quake-360p.webm" type="video/webm">
          <source src="file:///C:/Users/cpearce/Videos/dartmoor.mp4" type="video/mp4">
        </video><br>

So that's going to be playing http://pearce.org.nz/video/quake-720p.webm which is 1280x720 pixels, and scaling the video down to 160x90 pixels. We currently are still using our software "baked into Gecko" libvpx decoder to decode video, on the Otoro's wimpy CPU, so I'm not at all surprised that we can't play a hi-res video smoothly.

WONTFIX! It's ridiculous to expect a 1280x720 video to play smoothly on the Otoro. The H.264 hardware decoder on this device can't handle this, let alone a software decoder.
