MPEG2 stream available with no DRM?
It's called Freeview and any number of DVR's will record this high quality MPEG2 steam. It is then just a matter of transferring the file (e.g. Twinrip) and off to the P2P bypass all the BBC's copyright 'issues'. DRM is just there to make the average users life more difficult it has and will never protect the content from unauthorized distribution (its not illegal!).
