Radeon Through To TV

[cheops05]

Hi,

I'm trying to get mythtv to display at a resolution of 1024x576 but the radeon drivers won't let me clock to below 20Mhz the clock says valid ones are 20-400Mhz

There used to be an option that let you override the clock using this option so you could get display modes on a TV

Option "ForceMinDotClock" "15Mhz"

But Ati Seem to have got rid of it...

Anyone know how to get this to work by changing drivers which version etc....?

Thanks

Adrian
