Eric, Marcus,

I tested Marcus's patch but problem still exists. Without loading 
acpi_video mouse pointer doesn't move or moves very lately/slowly.
I can see highlighted applets in gnome panel. But pointer is still in 
the middle. But mplayer can use -vo xv for full screen playing.
With acpi_video mplayer can only use "sdl" for full screen playing.

I tried to apply Eric's patch but it didn't apply cleanly. I compared 
Marcus's and Eric's patch and it seemed to me almost the same.
So after testing marcus's patch problem still exists.

thanks,

Ganbold
