trouble streaming audio/video on VISTA

[gnu]

I installed Vista Business on my computer, with WMP 11.0.6, and after that, I began having trouble streaming both video and audio on my computer. I can't access services such as launch.yahoo or videos on any site - I didn't have this problem when I was running XP Pro, or even in previous installs of Vista.

I've tried disabling both my firewall and anti-virus, and tried each of the following streaming protocols UDP, TCP and HTTP, but am still unable to stream.

Does anyone have any suggestions about what I may have overlooked, or ways to let me stream music/video again? It's just this computer, my laptop with XP pro on it can access launch.yahoo just fine, so I know it's not my internet connection.

Im going way out on a limb but something you can look into is making sure Java and Flash is up to date.
