Ok, so the links that work have a URL that looks like:

The ones that are not working look like this:

Both play the same video just fine if you copy into a new browser tab, however only the first works within the Gallery

Ok, so help me understand what might be going on with this then. With the same Google Developer API code, I have existing videos that play just fine. If I create a new Gallery, import a link to one of the existing YouTube video’s that play fine, the video imports successfully. However when I try and preview the Gallery and play the video, it gives me an error (An error occurred. Please try again later). The original link to the same video still plays fine (from the other Gallery).
