Yes, there are many terms for the same thing. I used room because it is more generic than meeting/webinar/seminar/virtual classroom, and can apply to any of them. They all function the same, as far a recordings are concerned, so I try not to single one out. This tends to make the thread, and possible solution more useful in the future if someone else experiences the same problem. Sorry if that was confusing.
Not sure what is happening with that recording. It could be a bug, or it could be some permission setting, or something else entirely. I'd recommend working with Adobe directly to have them help identify the issue. Some of the support staff does find time to look over the forums, so they may reach out to you here, but you can always call support at 800-945-9120. If you are using a licensed deployment of Connect, then you should have a contact number on your support agreement.
