GATOS driver supports vsync for Xv, and AFAIK it's enabled by default.
This way mplayer "speed" depends on refresh rate. Decoding will be blocked
until vsync is reached. So you should disable vsync, or set up refresh
rate near (or a bit bigger) to n*fps where n is integer.

I think yes.

Do you write this docs? I like to include, but have no time to write it.
