None of the movies on the Roku channel will load...it looks like it’s about two and then goes right back to the previous screen. I saw a similar post earlier but there were no answers to the problem.
Have you tried removing and reinstalling the channel?
Remove/reinstall procedure:
1. Highlight channel on home screen.
2. Press * key and choose Remove channel option.
3. IMPORTANT- DON'T SKIP:
From home screen, Settings > System > System restart. This assures no remnant of the old installation remains in the Roku's memory so you get a complete reinstall. It may or may not make a difference, depending on what's causing your problem, but it's worth doing.
4. Reinstall the channel.
5. If channel requires a login, you may need to log in anew.
Note that a reinstalled station gets added to the bottom of the channel grid on the Roku home page.
