Flash playing up "/

Basically flash is being a pain in the backside. In Opera, youtube doesn't work at all (I get the upgrade your flash text instead of the video) and iplayer has no sound. Meanwhile in firefox youtube works fine but iplayer still doesnt have any sound. In both of them cnet tv works fine. i've uninstalled Opera and flash and reinstalled them both and it hasn't fixed it. I don't have sound issues with anything else on the computer and i didn't change any settings to make youtube not work in opera afaik.

Anyone got any ideas?

Ok I've just uninstalled flash via the control panel and restarted but cnet tv still plays in opera so it obv isn't uninstalled. Im confused now!
