Be very careful with iPlayer or SKY Anytime as they both use Kontiki peer-peer file sharing software. This mean that your PC is used to supply any downloaded programme to any other iplayer user who wants to download the file.
This slows down you internet connection and uses PC memory and proccessor resources.
If you really need to use iplayer, use a firewall and specify that Kontiki only gets internet access when you let it, or when the firewall is shut down.
