Re: Speaking from NZ
yes, but the licensing as UK only is a BBC decision, within the BBC's control, for stuff that is made for them. "We want you to make this for us, and we will own the rights." "Err, we'd like the ex-UK rights". "OK, we'll get someone else to make it then."
Doesn't address previous content - or content that the BBC Store "sold" via "buy now" buttons that have turned out to mean "rent, until we change our mind, sorry about lying to you on that" - but that cannot be an insurmountable issue. "Nice production company you have there, shame if something happened to it. Before we talk about any future work for you, let's clear up the silly question of rights for license-funded content."
