When I try to watch videos on youtube an error message is shown instead saying either javascript isnt turned on or the latest version of flash isnt installed.

I have installed the latest version of flash and made sure active scripts are enabled in internet options.

I cant think anything recent I have done that would have stopped it working.

I have the same problem.

Only on some PCs, namely the two at my Dad's. Even then, it seems to be intermittent, have it on some vids and not others.

If you find a fix, let me know as I've spent ages on it (including asking here!!! ).

Cheers,
James

I had a similar problem a little while back, try downloading and reinstalling the latest version of Directx from http://www.microsoft.com/downloads/Browse.aspx?displaylang=en&categoryid=2
