This is more likely a problem with Adobe Flash player, or whatever streaming player or plugin you are using and your browser. Check your browsers troubleshooting page for issues with players and the like. Mozilla has recently had all sorts of problems with their latest version of Firefox and the newest version of Flash player.
Its completely idiotic they cannot sort things like this out before the version is released, but it just doesn't happen.
I had to downgrade my PC to a previous version of flash player in order for any streaming video to work at all on my system.
