mplayer with TRIO 64V2 DX/GX card

[Joydeep Bakshi <hizibizi@spymac.com>]

Hi,
Is there any one in this list who is using mplayer with 'S3 TRIO 64V2 DX/GX'  
PCI VGA    ?
I have this card and Xfree86-4 server. I select x11 as driver with mplayer 
like 'mplayer -fs -vo x11 .........' but can't get the full scren. then I try 
'mplayer -fs -vo sdl .........' and this time I get the full screen but 
picture quality is poor. as-usually 'mplayer -fs -vo gl2 .........' provides 
too-slow frames.    below is my adaptor configuration of XFree86-4

Section "Device"
        Identifier      "trio"
        Driver          "s3"
        VideoRam     2048

could any user of mplayer with such card suggest a solution ?
PLEASE CC TO ME. THANKS
