Everything looks OK, except for dr (can lead to slowdowns) and menu
(major slowdown in some cases too).

Also, audio lags for me when using esd; but it may work good for you,
don't know.

WTF? Something is definitely broken here. pp should only take several
percents of cpu on your machine.

This should be 10 times slower..

I think I get it, dr leads to problems. It happens sometimes. Try
-vf pp,eq2 - it should be very fast. eq2 in the filter chain disables dr
(or removes the bad effect, don't know). Then just turn it off.

That won't help you with color problems, though.

Well, you should add some parameters to some of them...

OK, try to describe how colors are distorted one more time. And show
full output of mplayer -v movie.avi (till the playback starts).
