This won't make them all 16/9, but I think it will do for you. Go to Preference's, Advance, and in the space where it says "Run the following....." put aspect_none. That will make the video stretch to full screen. However, if you are watching from a video it does still change the size you need to turn off auto resize for that.
I know it is a bit late, but I saw this post while search for it myself, and thought who knows, maybe you havn't found a fix yet.
That's a great workaround. Tried that & it worked.

Lubuntu 14.04 Some people are funny. They spend money they don't have, to buy things they don't need, to impress people they don't even like.
