When I connect my wd box to my tv it blacks out every 10 secs very annoying. When we watch a dvd this doesn't happen. When we watch regular TV a blue box appears on the top right hand corner and again watching the wd box. Do I need to turn off a setting or could it be something else?

Air 2 is the source it's looking at for a signal - - where is the signal plugged into? and are you able to change the input or source to look at another?

There is no factory option to stop the box from poping up every time the signal changes, which is what is happening. It has something to do with signal strength or the fact that your cable box is not set up for HD. Call your cable company to get a tech out to check your signal and set up your cable box because they do not come pre-set with HD defaults.
