Help!! Problem w/ dvd?

I recently bought tangled on dvd off of ebay. It was brand new, but every time i play it (and this happens in every dvd player i've tried) an icon that looks like a camera ramdomly pops up at the top of the screen during movie play. It's really annoying and distracting from the film! Is there a way i can remove this or will i just have to go a store and buy a new one?? Thanks! ( please excuse any typing errors as i am on my ipod)
