All credit goes to Rattenbonker for creating the mod. I just made the random function.

TVLoader

Allows players to add custom videos to the Television.

You can easily create your own TV content pack by using the TV Pack Creator. It can be found here.

Create a custom mod, add a folder called plugins/Television Videos and put all your mp4 files in there.

Videos will be randomly selected from your videos folder instead of being played in alphanumeric order.
