After building a Microsoft Windows Media Center 2005 computer, it is quickly discovered that the video card does not have any compatible drivers.  The next obvious option is to use regular Microsoft Windows XP drivers.  Once installed, one may encounter serious incompatibility issues as it relates to DirectX 9 and Microsoft Windows Media Center 2005 will only operate in “safe mode”. To resolve this add the following two dword keys to the registry and Microsoft Windows Media Center 2005 will no longer open in “safe mode”.  I have tested this resolution successfully.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Media Center\Display Settings]
"DisableDxCheck"=dword:00000001
"DisableDx9CapsCheck"=dword:00000001
