I guess the default option for the H264 player under UI3 is HTML5. I've been having some issues with choppiness in UI3, and switching to Javascript solved the problem entirely
Is there a reason not to use Javascript? Are you guys using Javascript or HTML5?
I just learned this myself last week. It wasn't choppiness, but it was constantly refreshing with the HTML 5 setting. It was recommended that I try JavaScript, and it resolved my issues. I'd be curious as to when it is appropriate to use one over the other if it is anything other than the issues we were having.
