When enter an app on my roku express and begin to watch something the show/movie last between 3 to 5 minutes and I'm kicked out of the app to the roku home page. It does this with every app except Netflix. I've tried deleting the apps and starting over. I've tried updates and even returned it to factory settings and nothing works.
If you are powering your Roku by plugging into the USB port on the TV, try powering from house power via the USB power adapter that came with the Roku. Many USB ports only supply 0.5 amp which is not enough to power a Roku reliably.
If you don't have the Roku adapter handy, any other you have from another device should work as long as the fine print on it says it outputs at least 1 amp.
