Install TV Tuner Drivers

I use 4 Hauppauge USB WinTV-HVR-955Q TvV tuners. Each tuner can handle one stream. A stream can either be used to watch or record.

Step 1. Install Drivers

$ sudo add-apt-repository ppa:b-rad/kernel+mediatree+hauppauge

$ sudo apt-get update

$ sudo apt-get install linux-mediatree

$ sudo reboot
