There is also an API name change getTimeRanges -> getAvailableTimeRanges (for API introduced in 8, so should be OK). I'm thinking we might be able to perhaps find a better name there. It's all of the available time ranges in the recording, not necessarily only for the filtered collection. getOriginalTimeRanges?

getPreFilteringTimeRanges?
