I'm going to assume that he is indeed using the USB connection as another device wasn't listed in the original post. The SX41 camcorder records to flash memory. While you may have the correct drivers for this camcorder, the USB connection is only used to download clips that have already been recorded. There is no streaming through the USB. As far as I know, only tape based camcorders will stream through the USB (or Firewire). What you need to do is use the A/V port on the camcorder with a video capture/tuner device like the EasyCAP or Startech. There should be a cable that came with your Sony that connects to the proprietary a/v port and terminates in RCA composite and S-Video plugs. Those are the guys you'll be using to stream.
