Ways to link to IBM-Ustream in Articulate 360 products?

Hi, folks. I've been banging my head against the wall all day, trying to figure out how to get Rise (preferably, or if not, SL) 360 to integrate a video from the Ustream platform acquired by IBM Video Cloud / Enterprise Video Platform. These are massive, so uploading even one of them directly into Rise took for-EV-er, and it's still not done processing ... also figuring that won't bode well for SCORM file size and stability. :(

Unlike YouTube, Screencast, and others, a "plain ol' URL" doesn't "play nice." All I get from Rise is an ugly block that indicates nothing about the video/topic/content, and it forces open a separate browser tab -- won't display anything "in-line."

SL's Insert > Web Object gives me an even uglier block with an error message once published to Review, and I've not been able to ferret out the proper embed code for SL's Insert > Video.

I ran into this same issue last year with a different client, and we never did resolve it, having to conclude it was because the content was secured behind a "wall" and wasn't friendly to embedding in other platforms. Thoughts? Suggestions? Experiences? Confirmations of same non-results?

Thank you very much ~ Michael
