I just tried today's changes with my theme and also with official,
Blue Abstract.  With live TV wait set to 0, it works as expected.  If
live TV wait is set to 1000ms or more, the video never jumps back to
full size.  About 500ms seems to be the value where things break.  AT
<= 400ms, it usually works and at >= 600ms, it usually doesn't.
Again, this is with my Shield.  I just tested on my Linux desktop with
OpenGL rendering and it did the same thing.
