I am using an ADS Tech Instant TV Cardbus to interface with a wireless camera, using the TV tuner card's composit input. Informant recognises the card's drivers (713x BDA Analog Capture). By clicking on Device Settings under Properties, it shows that a signal is present if the camera is on, and shows the number of lines detected. Those values return to zero if I power the camera off. So, I know it's detecting the camera. However, Informant will not show me a picture or record. Any idea why?
