Nope. Two negatives do not equal a positive and you have witnessed that with the nerve-crushing experience of playing a video clip on your Facebook Timeline. First of all, it seems to be a battle of giants going on right now, between YouTube and Facebook, either one denying the other part's respond on their respective server. On the other hand, Windows, as the main operating system in the world, has gone from "hmmm" to "yuk", from XP, through Vista and 7, to Windows 8. Bottom line being that, two years from now, Windows OS will be just like a dust-buster that you would find in the closet at some point and you will have no idea what to make out of it.
As far as concerns the lag on your youtube shared videos on facebook, there's a simple resolve: refresh the page, or press F5 in the browser.
