I am aware of what nvidia cards support the hardware decoding for HD etc What about ATI cards anyone have a list ? I have an "ATI Sapphire 9600XT ultimate" and it appears that this card supports hardware decoding when I thought it was only the X series of ATI cards. Well the strange this is the hardware decoding work fine for TV, DVD etc but when I play any HD TS files in MCE I get a flicker every 3 or 4 seconds but if I play the TS file with WM player then its flawless ? I tried a mates nvidia 6200 card and that again plays fine with WM player but with MCE after "X" amount of time it will show the blue screen and say "media center has encountered an error cannot play the file." I did some tests on DVD and TV and could not nitice any difference between the 2 cards either in fact I thought the ATI was slighly better for displaying TV footage although this could be the default colour scheme, contrast etc are better on the ATI.
