I might be on to something.
I found something from a YouTube video:

When trying to grab the manifest code from this NBC Olympics link referenced above:

I downloaded Grab Any Media for AdobeHDS helper from that YouTube link.
I just don't know the exact code I need to paste into the top left of the image below where you put in the Manifest or Fragment code. Nothing seems to work. I keep trying all the codes I can grab, and I try to click on "Start" in the right (as circled in red) in the image below, but it won't do anything.
