For some reason I have video playback settings disabled (greyed-out radio button in 3dfx tools color management). Desktop/Glide/OpenGL/D3D color settings are working fine. Btw, this is with Voodoo3 2000 and Amigasport 3.0 on win XP SP2. I remember the option was available when I had win 98SE + Amigamerlin 2.9. Is there any way to enable the option? Why is it disabled?

I think this feature is not available in the amigasport.it should be fully operational in the latest SFFT v3 driver.if you want to try it out,just load SFFT via the device manager right on top of amigasport..
