Nothing moving here with git master nor debian's 3.4.9, does anyone else see this?
(Also, only a single "Movie-Aspect undefined"-line")

I confirm the behavior on 3.4.9

I do get multiple "Movie-Aspect undefined" lines.

I haven't had a chance to chase down the bug yet, maybe tonight.

btw- as a workaround switching mplayer to `-vo sdl` (or probably anything not -vo x11) should hold it still
