Get expatshield and the bbc iplayer stream will work. If you are on Vista or Win7, remember to install it as an administrator, or you will just be redirected to a dead link in your browser. So remember where the program saves the installation files, as you do not get the option to install as administrator on the initial web installation procedure. Also remember to do a thorough uninstall afterwards, as the program is a bit like malware.
It's only after we've lost everything, that we are free to do anything.
