Writing to one of the lists usually is more helpful, I took the liberty
to CC mplayer-cygwin (though I moved you to BCC, in case you don't want
you email address public, after all you didn't say why you contacted me
personally).

I am not aware of a major difference, but you can change the colors for
vo directx via the 1-8 keys and usually also via the control panel of
your graphics card drivers. Maybe you changed something there and all
other players just ignore those settings (or MPlayer ignores them).

Possible yes. But I doubt anyone will do it. So far a lot of contributions
to MPlayer's Windows support still comes from people that actually don't use
Windows anymore, so there is not much to expect. And this includes me.
I'm rarely motivated to boot windows just to fix MPlayer stuff.

You should receive the input messages by pressing CTRL while clicking. A
patch to change this behaviour is available (to move the window except
via title bar you would then have to press the ALT key), but so far there
was one person for and one person against the change - which is not
enough to convince me to make the change.

This is intentional and unlikely to be changed.

You are using pre8?
If it's not fixed I'll have another look at it. This is probably related
to another fix, before it would not allow the window to become bigger
than the screen size, resulting in a squished image (per default,
Windows does not allow windows to be bigger than screen size, bah).

Try setting the MPLAYER_CHARSET environment variable or the -msgcharset
options (also try "noconv"), but I'm not sure if it will help.

Known, more or less yes, intended probably not.

Your English definitely is good enough.
