My favorite feature of the Roku Media Player is the USB port. You can watch MP4, M4V, and MKV video files from a USB Drive. How do you watch those files though? Here are the steps:
1. Add the Roku USB Media Player Channel. You can add it to your account via the Roku website or find it under the Music or Photos & Video categories in the Channel Store.
2. Plug the USB drive into the USB port on the Roku.
3. Open the USB Media Player channel and select “Movies”.
4. A list of videos will appear. Select the one you want to watch and enjoy.
You can use the normal Play, Pause, Forward, and Rewind buttons just as you can with most other Roku channels.
