Hmm, it does for me, although I noticed before that his instance sometimes only wants to play videos after one reload of the page.

Maybe it works with a direct link to his instance? https://video.fosshq.org/w/b226a555-0b8e-4ca0-ad1c-1aa4cd34b8b5 - I usually just quickly link to videos from my home instance due to ease of use (share button or copy-pasting address bar contents).

It shouldn't really make a difference, though, essentially, the same video should be streaming from the same server(s).
