actually, thinking on it a bit today, I wonder if a special purpose format (something like [video broadcast] or something?) would be a good idea. this could make adding releases easier if we automatically mark recordings on this format as videos (see this similar ticket for DVD-Video), as well as making it clear from the release group page (and in the data in general) what the release in question is without requiring a disambiguation.
(mocked up with the Inspect feature on my browser, lol)
that said, I don’t know what opinions would be on Special Purpose Formats like this, since (at least to my knowledge) we don’t currently have any, and a solution like MBS-7017 might be a better solution for marking video recordings on the release editor
