1) The BBC did not want to put DRM on there programs (As I understand) but they were forced to but commercial companies.

2) The BBC has produces a test system, that works on the most popular combination of OS and Browser. So? What should they have done? It’s a TEST. Typical FSF fanbois, who need to grow up a bit, and accept that the best way to test somthing is minimise conflicts due to browser/OS combinations, work the bugs out of what they have and then worry about Browse/OS combinations later. Its what you do with any other web software (and exactly the combination I would start with)
