LSO ("Flash Cookies") and Media Player
Some users have noticed that they are no longer able to use the BBC's media player when they have disabled LSOs.
We have for some time employed LSOs in order to improve user experience of the media player by storing the last position of incompletely played programmes to enable the auto resume function and to remember a user's settings preferences. We also use them for statistical reporting to help us to better understand how our content is consumed. This reporting is on a strictly anonymous basis and we do not pass this data to any third parties. Users have always had the ability to disable LSOs so that this data is not stored, as explained in the Flash Cookies section on the BBC's Privacy site.
However, we are currently moving the media player to the latest version of ActionScript (an Adobe programming language) in order to deliver an improved media player. This is a complex process and will take several months of work by our technical teams. It means that for some of that time the media player will sit across both versions. The two versions of ActionScript are unable to speak to each other directly and we therefore need to use the LSOs as a tunnel to pass messages between the two.
We hope to be able to stop using LSOs for this technical purpose later this year but in the meantime you will not be able to disable LSOs without losing access to the BBC's media player. If you have disabled LSOs, you will need to re-enable them for the BBC website in order to use the media player.
Thanks for your patience while we complete this work.
