Open up the Main Menu.

 Find the “My Menu” section and click on “Organize a Program”.

You’ll be taken to a new screen, where you’ll want to click the “+” in the upper right hand corner. When prompted, give your series a title and then click the edit button on that series, you’ll be able to add videos that you’ve already uploaded into your series. You can reorder the order in which they play by just dragging them around.
