andreyua what is the problem? doesn't it play on monitor 2 or is it playing on monitor 2 and you want it on monitor 1?
if you want it on monitor 1 then remove the -adapter 2 and you should be fine.
also what are you system specs, what graphics card are you using etc.

You are right. The space between the link and "-adapter" is missing. I will correct this in the next version of the mplayer plugin.doesn't it play on monitor 2
I watch all my video on second monitor (TFT TV), and video from online not playing through mplayer on secondary monitor (TV). But all video (not online) playing through mplayer fine.
Reason (IMHO) - absence "space"
