[Goo.gl HAS BEEN SHUTDOWN, AND THIS GUIDE NO LONGER WORKS. SORRY! INFORMATION BELOW MAY NOT HELP YOU PLAY MOVIES. I DO NOT PLAY MACHINECRAFT ANYMORE. ASK YOUR COMMUNITY FOR HELP.]


To start off, you will need the URL of the video you wish to play in-game.

Go to YouTube, find the video you want, and then copy it's URL.

Next, go to a website where you can convert YouTube videos into downloadable MP4s.
A good one to use is keepvid.com

Paste (Crtl+V) the video's URL into the bar asking you to do so.

Press enter, and choose a video quality below.
(For showing purposes, please get the highest quality. If you're just playing music, keep it down at 144p.)
Go to dropbox.com next.

Dropbox is a online storage where you can upload files online.
If you have not created an account, please do so to continue.

Find the video on your PC, and upload it here.
(Wait until the video has been uploaded.)
Next, press Share when prompted to do so.

A window shall pop up, now follow my movements in the pictures below.
Finally, we are going to goo.gl
A website that shortens URLs.

When you pressed Copy Link earlier, it gave you a new wording on your board.
Go to goo.gl, and paste it into the prompted bar.
Very important: At the end of the URL, is some wording that reads "dl=0". Change this to "dl=1". Not doing this will make it impossible to stream the movie in-game.

Next, press Shorten URL, and await a window to pop up.

Copy the given link at the top.

Hurray! You now have a link which will play a movie of your choice IN-GAME! Time to show it in action!

First, find yourself a TV. ( I'm sorry, but I do not know how to build one. :< )
Or... don't if you're just playing music.

Next, enter the following command into chat:
>movie=

Add your tiny URL to the end of this command, and press enter. Then wait a few seconds....

Ta-da!
