Hi Edgar!
Thanks for the tip - this gets me 90% of the way there, as it gives a thumbnail with a link to the page at rstudio.com where the video is hosted.
Forgive me for bothering you on the remaining 10%: do you think it could be possible to fully embed an RStudio video from a page that is not at rstudio.com?
Just to be clear, your answer gets me what I need for now, so no-one need get too worked up on this question 
Thanks,
Ian
