9. If not, run regedit again and look for this entry:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display\000#\NVIDIA\DirectDraw\OverlayMode
10. Change the value for OverlayMode from 0 through 5, restarting and testing the TV application
each time.

If this does not help, and you have a card based on the Brooktree BT848 chipset, you can disable Overlay
mode until a fix is found by going into the following registry key:
HKEY_CLASSES_ROOT\bt848\Force Primary
and changing the default value from 0 to 1.

Finally, if all else fails, try loading two copies of your TV card application. The second instance of the
application may not show the problem. This may be the only way to fix the problem in Windows 2000.

Q. I can't run any Direct3D programs, but OpenGL programs run fine. How can I fix it?

If you have Windows 2000 installed and you use NetMeeting, this may be because you have Remote
Desktop Sharing enabled or NetMeeting is started or is improperly shut down. If you close NetMeeting,
this should fix the problem. You can read more about this in the following Microsoft Knowledge Base
article:
http://support.microsoft.com/support/kb/articles/Q260/5/65.ASP
You might like to try running and then quitting NetMeeting even if you don't usually use it - it may fix
the problem.

Note that this problem still appears sometimes when you are just running NetMeeting without Remote
Desktop Sharing enabled. This appears to be an NVIDIA driver issue - you will have to close
NetMeeting.


If you are using Windows XP, make sure you read the 'Hardware accelerated OpenGL doesn't seem to be
working at all in Windows XP. How can I fix it?' question.

If you previously had another graphics card installed before the GeForce, go to the following registry key
using regedit:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\OpenGLdrivers
and remove any keys except the RIVATNT key.
