first attempt of html video hd (and other) tags

It seems like there could be a way to make videos play hd or not hd using html5 video. I would like to add more controls that allow the viewer to switch from hd to normal definition and back again. I would also like to explore the idea of adding more controls in general.This is my first attempt at discovering whether I can accomplish this or not.This is an episode of Sherlock Holmes via the Internet Archive. It is in the public domain.

I seem to lack the knowledge to connect the buttons to the player. Hmm...that is a critical step I'm missing, but if I gain that ability, I'll come back to this post.Until then, I have removed the buttons, but left the video up for any who come upon it and care to watch this episode of Sherlock Holmes

Another test, as my method didn't work on some other site.

A certain blog hosting service, that will remain nameless, didn't accept my html code for video. Just to prove that it should work, I am attempting to post the same video here. I may attempt to embellish it, as I have done on a third site with a different source video.The video below, should it work, will be a version of Robin hood made for TV in the 1950s.Problem is, the posts all end up with the same css style for video. In other words, I end up doing one post, and all the videos have the same color border and background. Why? Again, Chrome and Firefox are best. Added another file that should play on tablets and phones...maybe.Video should be updated to play on tablets. Will test periodically.
