I have a Plextor ConvertX™PX-AV200U unit and connect the yellow Video In connector to my NTSC camera. All I need to do is to view the camera image in real time. However, when I start the Plextor viewer software it freezes on me. I tried on a different laptop and I could see the image, however, the software froze whenever I wanted to close it. Any help would be appreciated. Jerome.
