Help After the 4.0.3 upgrade no website video

[korgms20]

Hi guys

Could anyone help me out on this?
After i have upgraded to ICS 4.0.3 i cant watch youtube videos on different websites (i can directly). After i press on the video i just get a black screen and thats it. Both on the default browser and on the Opera really gets on my nerves. Anyhow to roll back to prev. version?

Thx in advance everyone

Check that you have the latest flash player installed from the Play store. Try dolphin browser HD or Chrome Beta as alternate browsers, they might solve the problem too.
