Can some one help me.......I am starting to get worried that the tv capture card I got might be a dud. I have put it in the tower unit and tryed to install the software but it still does not work.It shows up in the device manager under Other Devices but has a yellow mark next to it. When I run the program it says it can not find a capture device.I will be very happy if some one could help me out on this matter.
