At http://www.betaone.net/forum/archive/?t-13854.html I found the following: "Also, the drivers probably MUST be DirectX 9 drivers. Run DXDIAG and check on the "Display" tab if it really says: "DDI Version: 9 (or higher)". If the number is lower than 9, your display driver is not a DirectX 9 driver." Well, I ran DXDIAG, and not only does the Display tab say "DDI Version: 9 (or higher)", but the System tab says "DirectX Version: 9.0c". So that's not the problem, but it doesn't explain why I have to add the registry keys, and when I do, why the screen goes black. And since the card has 64 MB of DDR memory, I shouldn't have to go through the 15 steps listed in the very 1st message, the purpose of which is to allow MCE to run on a 32 MB video card. Still stumped ....

flupke wrote, "That you get a black screen is not because of these registry keys but because of drivers." That is the part that I don't fully understand. I understand why adding "DisableDxCheck" and "DisableDx9CapsCheck" to the registry keys allows Windows MCE to believe believe the graphics card is compatible, but what is it about those values that turns a perfectly good TV screen black? Why is it that everything except the mouse pointer (which constantly flickers) disappears?

flupke wrote, "I don't really know haw to solve it but try the most recent drivers for XP but not the ones for XP Media Center Edition." I added the 2 registry keys again, and then downloaded the latest Win XP driver (22.2 MB) on the Diamond Stealth driver page. It didn't help, and they haven't answered my email. The installation program changed my driver from 8.252.0.0, dated 5/3/2006, to 6.14.10.6525, dated 3/22/2005. The Media Center screen is still black. The ATI Driver web site has past versions of CATALYST for Windows XP drivers from 5.1 to 6.8. Do I need to keep going back and trying the old drivers to see if they will work, or is there a simple way to accomplish this? I can't see live TV or view previously recorded programs, which sort of defeats the whole purpose of having a MCE machine.

I have just purchased a Stealth S60 graphics card ("featuring Radeon 7000"), which has 64 MB of video memory. I put it into a computer running Windows MCE because the motherboard has an on-board graphics chip with no connector for my TV set. I too am getting the "Your video card or drivers are not compatible with Media Center" message before the program will run (the "Not Desgined For Media Center" dialog box is already unticked). I tried Francesco's fix of adding DisableDxCheck and DisableDx9CapsCheck, but like niklasfin, when I did that and started Media Center, the screen went black (except for the cursor), and I had to press ALT+F4 to end the program. I searched ATI's Customer Support (hah!) database for help, but this problem was not mentioned. No drivers for this card were shown either. I finally found a list of graphics cards that they recommend for MCE at http://www.ati.com/buy/promotions/mcesolutions/ and of course, my card isn't listed. Has anyone found a way yet to get around this problem?
