It seems that (as illustrated by @anjacks0n’s success with one of your example objects) the main issue your decribing is caused by not having an appropriate interaction environment. This can (I think we agree- clearly) be solved by finding and maintaining that interaction environment.
It does highlight the question of how we identify what that interaction environment might be if we don’t get that information from the content creator (which ideally we should).
Validation seems useful for identifying what environment you might need. For example you could map “risks” to commonly related interaction environments to try to identify what environment you should be using to interact with the “risky” content.

Yes, it played – the colour bar scrolled horizontally in an old-school-demo fashion (I’ll tweet the screenshots). I’m using Adobe Reader X 10.1.14, but I think it might be being on a Mac that makes the difference?

Hmm, interesting. But does it actually play after clicking on it (your screenshot only shows the initial view after opening, and this looks identical ton what I’m getting myself)? BTW I also tried this with Acrobat Reader XI, for which I’m getting identical results.

BTW, your embedded_video_quicktime,pdf works fine for me! (Adobe Reader on OS X — Apple Preview didn’t like it). See https://twitter.com/anjacks0n/status/621285002865733632 for a screenshot.
