Hello Everyone- I was wondering if anyone could help me with an individual project. I wanted to connect one of those general webcams that output digital USB to something that requires analog s-video. Is there such a device? It would have to be a digital and analog converter, specifically USB digital convert to analog S-video, or some sort of analog output. I don't think it necessarily has to be s-video, but some sort of analog signal. Thanks in advance.
