iPad suddenly auto locks when using Channels

I have never had this issue before, but today when I am watching Channels on the iPad, the app seems to honor the auto lock setting for non-video apps -- it goes a little dark, and then the iPad shuts down if you don't tap the screen.

Have used the app for a while and never encountered this before. I haven't made any changes to the auto lock setting. I would appreciate any help.

This is a bug that was introduced with version 5.0.1. Please visit the app store and update to version 5.1.0 to resolve it.
