Force HTML5 on AOSP Browser?

view story

http://forum.xda-developers.com – I'm wondering if it is possible to use only html5 on the AOSP browser. I don't like that the flash on it now plays videos more pixelated than normal.If i go and view the same flash video with an only html5/non-flash browser, like chrome, it plays much more clearly. Alternatively I would like to have it switch to the YouTube app like chrome does when you click on a youtube video. (HowTos)
