I an not 'circumventing' anything.
Says the man who said "I need to pay for a programme to remove the DRM"
DRM is there for a reason. Probably due to the BBCs upstream agreements with the rights holders over electronic distribution of their content.
I'm not going to tell you what to ask Mr Google, because I don't know off the top of my head as circumventing DRM is not something I do. But put it this way, I'm sure its a popular question that no doubt many have offered "solutions" for, therefore it shouldn't be rocket science to find an answer.
Also, cut the license holder argument. The clue is in the word license. Just like Microsoft software, you don't own it, you license it .... the provider sets the terms.
Edit to add, as per the iPlayer terms and conditions published on the iPlayer website :
So that the BBC can meet its obligations to third parties who own rights in BBC Content, the BBC may embed digital rights management security in BBC Online Services or BBC Content and/or use other content-protection measures. You may not adjust or circumvent or try to adjust or circumvent these technical measures.
