ooo my first question i get to answer, how fun!

so to answer your question, when you go to view a flash video do you use firefox? i'm assuming you do since that is the default browser ( i have bt4 on my netbook ) are you aware that they have no-script installed with firefox? if you go to the website of the flash video you wish to see, look in the botton status bar of firefox, look all the way to the left and you'll see a little icon that is an S with a circle and a slash through it as if to say "NO S" if you click on that, it brings up a menu...from there you can proceed to "Allow" the webpages javascript and thus enabling the flash video to play.

Hope this helps,
