I am using the an AIW 9700 Pro in my HTPC. My display device is a 43" panasonic plasma. DVD's, Game...etc. look best at an 852x480 resolutiion on my plasma..... I noticed that there have been some HDTV resolutions added to the 3.10's by Omega... but not the one that I need

... how would I go about adding that resolution so that it is selectable when I click on the adapter tab and then click on "List all modes"
The 852x480 resolution is available in the 3.6 Catalyst drivers from ATI, but seems to be missing in all subsequent releases.... any advice or help would be greatly appreciated....
