Hulu just started going back to the home screen today. Is there any way to fix this?
You didnt mention your Roku model # or firmware version (Settings/System/About) or Hulu app version (highlight the app and press Options (*) on the remote).
The Hulu app updated today to version 6.48.1 - the update may have corrupted your installation.
Try reinstalling Hulu:
1) Remove the Hulu app (Highlight the app, press the Options (*) button on the remote, then Remove)
2) RESTART the Roku (Settings/System/System restart/Restart) <-- MUST DO THIS HERE!!!
3) Re-install the Hulu app
(If you dont restart after removal, settings/cached data associated with the app are left behind and it wont be a clean re-install)
