You missed my earlier Post ...
It is not necessary that the video you see has to be in Flash ...
There are many different video rendering formats (and flash is worst of them)
Android browser supports many different video rendering formats like H264 ( to be technical ! )!
Many websites you visit automatically detect that you are using a android browser and render there videos in one of the supported formats ...
You do not notice any change ! this stuff is done almost automatically when u use a mobile device ...
You cannot Update that Stuff as it is not officially compatible with ur device

Btw try the browser i just posted ... It should work fine !
