The BBC Trust has responsibility for ensuring that the correct degree of scrutiny is given to all proposals from the BBC Executive for new services (such as the iPlayer) and any significant changes to existing services.In the case of the iPlayer, following the consultation, the Trust noted the strong public demand for the service to be available on a variety of operating systems.

The BBC Trust has asked to meet open source advocates to discuss their complaints over the corporation's Windows-only on demand broadband TV service, iPlayer.

The new BBC iPlayer went live at around 5.00pm today...the streaming service is for all, whatever OS you’re using, as long as it’s got Flash support.

"The Open Source Consortium (OSC) is to meet with the BBC Trust--the broadcaster's independent governing body--to discuss concerns about a cross platform version of the Beeb's iPlayer."

The BBC have activated a protection mechanism on Flash based streaming system used by iPlayer, stopping open source media players from legally playing BBC content

The BBC is being threatened with an anti-trust challenge in Europe over its use of the Windows Media format in its on demand service, iPlayer, which is in the final stages of testing.

The BBC Trust met with the Open Source Consortium (OSC) yesterday to discuss the controversy raised by the BBC's iPlayer, which will only work on Windows XP.

The BBC's iPlayer site has been a target of open source community ire since it started. Originally delivering content via Microsoft DRM-protected technologies, it was condemned by the FSF (among others) for dictating unfree technology choices on viewers.

Just hours after the BBC said it had fixed the iPlayer streamed TV service to prevent DRM-free file downloads, a London-based programmer has bypassed the new protection.
