Oh no, not kontiki!
"The kontiki client (kservice.exe) continues to run when a user closes the iplayer and uses the user's broadband service to provide other users with content. This can be particularly troublesome for users with Broadband connections that include a capped monthly download limit." http://en.wikipedia.org/wiki/Kontiki
Also, kontiki likes to use up plenty of CPU while sitting around in the background as a service...
