So, I built something to be utilized as a "Featured Videos" shadow-box on the video page.  When I got started, (and not being totally familiar with the limitations of C5), I utilized the >html< block to add the content currently found there.   Now keep in mind, what's there was intended to be an infinite scroll navigation for video thumbnails.  However, and as of now,the static size of the shadow-box needs to be adjusted via CSS @media queries relative to the clients screen size and orientation;  And after working on it the better part of an entire afternoon, I decided that it would be more equitable if it were built within it's own block so as to re-use it else where on the site as needed.
  That is,,, If I decide to use that YouTube API feature at all.  You see, when they first rolled that out, (click a thumbnail and direct to a fullscreen view,,,  commercial free,,,  and when you were done it would navigate back to the referencing site.  Now when you minimize the screen after the video's complete, it navigates back to YouTube;  And that's what they call click_jacking. 
So I'm going to look at it and see how to mitigate against such efforts, (like featuring only non-monitized videos ;-)

So until then or whenever I get some new and different components completed, I'll post back here.

Thanks for checking in,
