Usually, TV tuner drivers come as part of a package that also contains the video playback software. When bugs are found in the software, developers launch new drivers meant to solve these issues and improve compatibility with newer operating systems, as well as add new features to the device.
Whether you are using an external or an internal TV Tuner, it is very important that you update your drivers as often as possible in order to use your device at its maximum potential. TV Tuner drivers act as a communication bridge between your TV tuner and your personal computer.
