Hi Mike, Jonathan form Silverstream here. Thank-you for your work on this.

Just a quick note, the video_key uids are for matching the iframe with the JavaScript and the variables for height and aspect ratio passed to it. This is for cases where there is more than one video on the page with different player sizes. They doesn’t really have any significance beyond that and can just be any unique string e.g. generated with PHP’s uniqid() function, they just have to match.

All the best
