The new page is much better and much more up to date. I see that 
xorg.conf option listed now. Thanks for all the work. There are a couple 
of errors though, so I went ahead and made the minor corrections. The 
xorg.conf options should go in the "Device" section not the "Driver" 
section. Using the "Driver" section will result in an error and crash X. 
Also 'End Section' needed to be changed to 'EndSection' (no space) in 
two places. I added a comment indicating the Option "XvmcUsesTextures" 
is used for the Chromakey fix to get a color OSD. I personally had to 
disable this option because it causes the left and top side of the 
screen to have a few pixels of solid blue during playback. So it may not 
be a good idea to tell everybody to enable this option especially if it 
only applies to series 4/5 cards. It might be better placed under the 
OSD chromakey section.
