I have about about three terabytes of movies and television saved on an external hard drive plugged into my parent's main television. It's about as simple as a dvd player to use, but they don't use it. I need a way to make it as easy as watching cable. It has be constantly playing at random so that if they want to watch something they can just change the channel to HDM1 and there will be something playing. Any way this can be done?
