I'm facing a problem in my GoblinXNA program which is the screen resolution, if im using 480*640 everything is fine and my application is working perfectly

captureDevice.InitVideoCapture(0, FrameRate._60Hz, Resolution._640x480, ImageFormat.R8G8B8_24, false);

but if i change that to 800x600 or 1280x1024 like this:

captureDevice.InitVideoCapture(0, FrameRate._60Hz, Resolution._800x600, ImageFormat.R8G8B8_24, false);


i get an exception

GoblinXNA.GoblinException was unhandled      Message=Could not start video stream    Could not setup graph    Error HRESULT E_FAIL has been returned from a call to a COM component.

I managed to fix the problem by Changing the resolution in DirectShowCapture.cs to 1280x720


Thank you
