The capture device you're identifying in this aspect of the Setup Wizard is the TV tuner card to which you've connected your broadcast source. The Setup Wizard may identify other video capture devices, such as a web cam or additional video capture card, which are installed in or connected to your PC. If you see multiple capture devices in the list, ensure you select the capture device that corresponds to the TV tuner card that Beyond TV 3.5 will use.
Note: If no capture devices appear in the list, check the installation of your TV tuner card (hardware) and the drivers (software) associated with this device.
