This is closely related to member Microsoftee's topic re: DVR camera not recognized.
My surveillance camera, a Swann Night Hawk SW-P-WOC, worked perfectly when connected to an old VCR. Now, when connected to a EasyCAP USB device, it appears briefly, then shows "unplugged" before I can do any video capture with EyeLine. Apparently the drivers out there for this EasyCAP are many, and not reliable. I finally found one that installs without errors in Windows XP (service pack 3). I've spent hours searching the web, and there are a lot of unhappy campers out there. Maybe I'll learn that I just made a bad choice in purchasing this USB device. Any help will be appreciated.
