I want to download a show so I can watch it without using my data.
You can't download anything using a Roku device or the mobile app. If you've downloaded something by some other means, you may be able to play it on your Roku device using the Roku Media Player.
As noted, Roku's have no internal storage or ability to download. With most Roku's, you may be able to put it on a computer and enable a media server so you can use Roku Media Player to view it. With the Ultra, and maybe some TV's, you can put it on a USB drive or stick and view it.
