XV on Intel i810

[James A R Brown]

Hi, I have spent hours trying to sort this one, asked in forums
(Fedora8) for my distro and no luck. So I have come back to the start ;)

I am trying to get xv working on a Dell Dimension 2400, it has a single
std monitor outlet and no AGP on the main board (although there are what
looks like a space and solder points on the mainboard where you would
expect the AGP)
        
mplayer -vo x11 film.mpg works fine, but the CPU (2.6GHZ Celron) can't
keep up on this if other tasks are running.
        
mplayer -vo xv film.mpg does not work, it brings up the blue screen, but
running gxvattr or xvattr you can mess around and change the blue, so my
feeling is that xv is working, but the pipe is not coming through.
        
I have tried manually setting the pipe via xvattr -a XV_PIPE -v 0. This
makes no difference. At present it is back to -1 which I understand is
automatic.
        
xvattr -a XV_PIPE -v 1 will not work, it just defaults back to -1. 
        
Memory is 1gb and have allocated 256mb of this to video in bios.
        
The options in xorg.conf shown are stuff I tried from Mythtv
suggestions.
        
I have also tried with the "intel" driver in Fedora settings, no luck.
        
Does anyone have any suggestions on howto debug / resolve this? 
        
Thanks
        
James
