Video plays on one page and not on another

Hello,

A strange situation . . .

It is a the same (test) post. I have 2 ways to go to these eBook pages, 1) directly via blog/archive page; and 2) via Drop Down Menu by Category. The video plays great with no problem by method 1), but by method 2), it is just a still photo of the thumbnail image of the video.

I need this Category way of posting because it a chapter of a book, listing it under the book title. Why is it not working? Any solution?

Please see what I mean:
