OK.  I thought maybe it was a variant mp4, but I see that you are right.  It
is the browser support for the page not the codec.

To be clear, I am using browse in both the case where the video plays and
the case where it doesn't.  But your point about the html and javascript
that wrap the video that doesn't play is a good one.  I had already tried
looking at the source, but nothing jumps out.  Thanks for the alternative
ways of trying the page on the xo4.  

But if this is the answer then I'm pretty much stuck unless browse can be
modified to handle what other browsers can handle.  The page in question
starts at TED, is wrapped in a zim file by kiwix, and rendered by the kiwix
server.

My plan is to put a server on the open internet that has this page, but I
haven't gotten to it yet.  I'll let you know if you're interested.
