I have the same problem. The installation wizard sees the DCS-910, but dview does not. UPnP is enabled on the camera, router and PC. The browser connects using ActiveX and Java, but dview cannot find the camera. I manually added the camera in dview, but still nothing. I have firmware 1.01. Does dview not recognize the subnet mask? Is dview using a port that is blocked? Dview is on my list of exceptions in the Windows firewall.
