Problem:-

When I start Media Center 2005  I get this message:-

Your video card or drivers are not compatible with Media Center

Resolution:-

To stop this error one need to have a graphic card which is DirectX 9.0C compliant.Visit the manufacturer’s site to download and install the latest driver.Also check and update the decoder installed.

 Registry tweak to stop the error message:-

To do this:-

Start>Run>Regedit>OK

Locate the following registry location:-

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Display Settings

Here you have to add two DWORD keys  DisableDxCheck and DisableDx9CapsCheck having value 1 for both the keys.

Drawback of this registry edit:-

it will just stop the error message appearing but the black screen during watching TV will continue.

So the ultimate soution is to acquire a DirectX 9.0C  compatible graphic card.
