[MPlayer-users] [question] Can i use fullscreen matrox dual head??

Hello MPlayer I have two vga cards - matrox G550 dual header and S3 - and use three moniters. But i can view on primary monitor- of course can do on S3 vga, third display - . I want to view matrox secondary header mplayer- of course primary - . can i view mplayer which runs full screen on which primary display and second?? Thanks.. P.S i have been tried matrox tv out mod but in my kernel (2.4.21) that doesn't run. and matroxset cannot run. Of course i compiled mga_vid.o and it is succefully. the program, matroxset, cannot get parmetars passing ioctl system call. Kernel : 2.4.21 ( patched xfs, NFS tcp) Mplayer: 2003 07 08 cvs version desktop: KDE 2003 06 16 cvs version XFree86 - 4.2.1
