Help!/How are livestreams covered?

What with Big Finish having launched one for their 20th anniversary, I'd like to ask how, if at all, livestreams such as this are to be covered on Tardis.

Since it's mostly a medium for rereleasing preexisting audio stories (or, as the case may be, single episodes of them), it doesn't feel right to me to cover it like a single webcast; but we really ought to do something, because there are also original behind-the-scenes featurettes packaged in, none of which have an individual name or credits. They may be of some use for sourcing of real-world info.

There are also little looped CGI animations running while the audio is on, including, for example, an animated appearance by a Tenth Planet Cyberman who walked on-screen and then went away while Spare Parts was on. Something like the two Yule Logs in format. Where, if any, would it be appropriate to list these easter-eggs?
