When I watch this YouTube video it's in Flash.
But when I click on this other video – that video is in HTML5.
Why are some videos in Flash and some in HTML5? Also how can I force HTML5 for videos (for example, when I want to use the speed-up feature)?

The issue with the first example is that you are not going straight to the video. Instead of watching as part of a playlist, view the video only:

This is the full URL:
http://www.youtube.com/watch?v=KqnB2Ew0SFM
Now you'll get all the features supported by HTML5.
