If you don't live in the US, I recommend just buying from a high rated seller on eBay.

The instructions are japanese but once installed, it works absolutely fine with all your standard recording software. It handles both Composite and S-Video really well (Bit of irony there since Composite is crap) and they're very affordable. The IOData GV-USB2 is by far the best budget capture card for retro games. I have used it for over 2-3 years without any issues at all. i recommend The GV-USB2 as a capture device. If either of those doesn't work at all then its the device. Try to uninstall the version you have on your pc and install a older version of firmware if you can find it. The only other thing i can think of is the firmware version is messed up of your capture card. Sometimes this can cause conflicts when trying to install the proper drivers and prevent windows from installing the proper driver. Uninstall all the ones that are labeled ' unknown device' What happens when you get ' Ghost Usbs ' for example when you connect a mouse and Windows doesn’t properly install the drivers for you it keeps the failed install of the driver on your pc. One of the last options on the manager should be ' Universal serial bus controllers ' If you have any ' Ghost Usb drivers ' they should be grayed out there. Click that option to see all the hidden devices on your pc. If you go to ' Device Manager ' on your pc ( which either is found in the control panel or typing devmgmt.msc in run ) and under the view tab you should see something labeled ' Show hidden devices '. Windows as you know should update drivers and install them on their own. Sounds like to me you are having a issue with ' ghost USB devices '
