What is wrong with my PSP web browser?

I want to go on YouTube to watch videos and it says i have Javascript off or sont have my Flash updated. I go to my View Settings and even back home settings to turn both Flash ans Javascript on and it still wont work. No videos from any site work, youtube, break.com, besttube.com, nothing works. Sometimes it even says i am low on memory ans to turen on Conserve Memory in the view settings area. I did that already and it still wont work. And on YouTube when it says click here to upgrade to flah my PSP freezes on the site! What the hell is going on!?!
