Interesting debate.
BOAC, from my understanding, and as you said in post 12, the TV licence allows for:
A TV Licence is a legal permission to install or use television receiving equipment (e.g. TVs, computers, mobile phones, games consoles, digital boxes and DVD/VHS recorders) to watch or record television programmes, as they are being shown on TV.
So you can watch TV, or watch an iPlayer stream live concurrently with a TV broadcast, which is covered by the TV licence.
Downloading a program on demand from iPlayer is not covered by the TV licence. A TV licence is not required for this. However, this also means that you are subject to any licencing restrictions put on that particular content by the rights' holder.
Also, in the BBC Online Terms of Use, linked through from iPlayer.....
(d) You agree to use BBC Online Services and access, download, view and/or listen to BBC Content as supplied to you by the BBC and you may not assist anyone to, or attempt to, reverse engineer, decompile, disassemble, adapt, modify, copy, reproduce, lend, hire, rent, perform, sub-license, make available to the public, create derivative works from, broadcast, distribute, commercially exploit, transmit or otherwise use in any way BBC Online Services and/or BBC Content in whole or in part except to the extent permitted in these Terms of Use, any relevant Additional Terms and at law.
4.2 Digital Rights Management
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.
IMHO the 'I pay the licence fee, therefore I should be able to do what I want with the BBC's content' doesn't stack up. Where is the line drawn? I purchased some Attenborough documentaries on DVD last year. Should the BBC have given them to me for free?
