I'm afraid that you won't - at least you won't do so legally. Your TV licence permits you to watch and/or listen to transmitted content, and to record it via an aerial for your own use only.
"not to attempt to, or assist any other person to, copy, reproduce, lend, hire, broadcast, distribute or transmit in any other way the BBC Content in whole or in part other than by using the "Link to this Feature"or as permitted in these Terms or to circumvent or remove the digital rights security measures embedded in the BBC Content; not to attempt to, or assist any other person to reverse engineer, de-compile, disassemble, alter, duplicate, modify, rent, lease, loan, sub-licence, make copies, create derivative works from, distribute or provide others with the BBC iPlayer Download Manager in whole or part, except as expressly permitted in these Terms and to the extent permitted by law."
Which means you may not do what you're intending to do, and we're not going to offer you any advice on how to act illegally.
I'm not talking about illegally copying dvd's or anything like that .Whilst I respect your comments as a forum editor afraid I consider that rule to be in breach of my rights. If not Legally then at least Morally
