[MPlayer-matrox] Error in config ioctl using mga_vid

[vongvibool at yahoo.com]

Thanks for the reply.  I tried one more thing by recompiling mplayer and replacing
the mga_vid source files in the libvo directory with the source files from the mga_vid
tarball.  The result was 
[MGA] mismatch between kernel (1) and MPlayer (514) mga_vid driver versions
so it is as you said, a mismatch with the kernel.  Now I will try to find where in the kernel
is causing this mismatch with ioctl.

It looks like you are using a very outdated version of mga_vid
together with a current mga_vid_test.
I changed in May 2008 the ioctl interface of mga_vid, which means
that if you are using such an old kernel, you have to use the
same mga_vid.h to compile your application with. Otherwise
you'll run into ioctl problems.
