All your settings look pretty normal to me.

All three videos play fine here with AMD graphics (and no
mplayer messages about issues at all) so I doubt the video itself is to
blame, but I think you already know that.

You'll probably need to talk to the mplayer devs directly to get to the
bottom of this one. I assume you did all the obvious things already
like nvidia vs nouveau drivers, test with all GL types you have,
compare released mplayer with latest from svn, etc etc etc ?
