Yes, the libs mplayer uses are often more difficult on cygwin than
mplayer itself.  This is why we really need a nativer directx vo.

the gcc2 package is gcc-2.95 series.  this is useful to install if you
install the gcc package with a gcc-3 version, so that you can have both
gcc versions installed at once.

.dll libs need to be in the PATH or other bin directories, but other
types of libs should be kept in /usr/lib and /usr/local/lib

Please send a full bugreport with a debugging build of mplayer and a
gdb backtrace and verbose log if you have not already done so.

Yeah, I don't use gcc3 on cygwin yet.  2.95 is plenty good enough, and
there seem to be too many issues remaining with gcc3 for my tastes.

!!!  Please tell me what went wrong with mpdvdkit and what you changed
in your personal source tree.  Mpdvdkit on cygwin is very important to
me, so let me know if there's something I can fix.

I have no experience with ggi.  Sorry.

I suspect it's just that the cygwin X server is unaccellerated.
Is this correct?  I don't use cygwin X11.

Hope I can help more soon, but I'm _still_ without a cygwin
shell for testing.
