A little weird. I am able to launch the movies from within the Movie House channel/app just fine on my US based Ultra 4660. I am launching them directly from within the device.
I do remember the Remote app but only briefly used it to test it. I don't even see it in the Play Store anymore. With that and themoviehouse.tv site being down, I am assuming some issues going on.
Edited to add... If you don't care about being logged in, then try Removing channel, Restarting the device, and Reinstalling the channel. When the channel opens, select the green box to start watching movies for free. (don't select the sign-in box). Maybe with the issues going on, being logged in is your culprit as to why the channel won't load. Without being logged in, you will likely not have any access to your rewards, but hopefully the free content becomes available to you if that is what you are after.
