Most Likely Causes:

1.  Windows XP Home (MEDIA CENTER EDITION) - Media Center runs a capture driver in the background...which can conflict with SE program.

2.  SE Drivers are not fully loaded - Check in the Device Manager for any Unknown Devices, or for any exclamation marks next to the Security Eyes Drivers (under Sound, Video and Game Controllers section).

3.  System set to PAL instead of NTSC in the "System Settings"

4.  No Video Signal

5.  Video Drivers not loaded or not loaded properly or using an Unsupported Video Card

In Security Eyes Software - Click on the Snapshot button (looks like a "35mm Camera" on the right of the camera panes).  If it shows a thumbnail of the camera, then you can eliminate #2, #3, #4 from above)  This leaves just the Video card or Video Card Drivers and Windows XP Media Center Edition...so double-check these Options.  If the thumbnail of the camera is a Blue-Screen as well, then the most likely causes are #2, #3 or #4 from above.
