As Michi said, it could be the upload tool, not the video. I don't think it's the upload tool going awry, as I tried a different video from the same YouTube creator, and it worked. I think it's just whatever kind of regex searches or whatever that they're doing behind-the-scenes, those are what is probably blocking it.

But yes, try it anyway, see if another video works -- you never know!
