I believe so. I thought adBreaks was in the sample url feed but I checked again and don't see it. Thought there was a post about it where I saw the syntax but can't find it. I think that's it though. It's camelcase tho, "adBreaks".
Interesting question about live TV. Not sure how you'd interact an ad break. Even if you did type 00:15:00, 00:30:00 etc it wouldn't work well being live TV it's difficult to goto commercial break exactly on queue. It could be RAF doesn't work with live tv breaks. Are you going thru a vendor like Livestream? Do they offer ad inventory or outsource to 3rd parties who do? Might be worth checking into them if they do.
