This is irksome.

Throughout having different versions of Opera and Flash installed I have been unable to watch videos properly. This is because a little pause or hang occurs to the video (not sound) while playing. This occurs on iPlayer, BBC Sports' website, youtube - anything.

I try loading up the video's page in I.E. and the hang goes away.

The version of Opera is usually the latest, and so is Flash's. Restarting the browser, reinstalling both (even using Flash's own Uninstall tool first), using Opera's "identify as.." and "masquerade as..." functions don't seem to solve the problem. I'm having this issue across two machines. Does anybody know what is causing it?
