Since it is a projector, it is much more comfortable to watch the video when it is aligned to the bottom edge of the screen, thus having a big black bar at the top of the screen.

You asked at LinuxTag, right?
I implemented that feature while there (a percentage option) but didn't manage to meet you again. Forgot the exact name of the option, I'll check later if I you can't find it in the docs or the commit log.
