The BBC has been told that it must offer a version of its iPlayer which will work on all operating systems and not just be confined to Windows.

When the BBC initially asked the BBC Trust for approval to create the iPlayer, it was told that "catch-up television over the internet should become platform neutral within a reasonable time frame" but even offering a stripped down version Flash version which it announced yesterday did cut any ice with the trust.

Now the beeb has to step up plans for it's Mac and Linux versions of the iPlayer, but one of the problems could be it's use of DRM which it uses on the Windows version to only allow users to store content for 30 days. DRM isn't licensed on the Mac OS as yet and isn't available for versions of Linux so it will be interesting to see what is planned, although don't hope for a non-DRM Windows version just yet.
