I'm wondering if there's any way a manufacturer/studio will replace a defective DVD? I had just opened the 'Bob Newhart Show 1st season' which I purchased 2 years ago and one of the DVD is scuffed and unplayable. Obviously it's too late to return it to the store. With everyone buying DVDs and not getting around to watch them right away, I can see this being a common problem. I'm wondering if certain studios have customer service departments that will allow you to return a defective disc and get a replacement. I know that Brentwood/BCI is pretty good about doing it, but what about 20th century Fox? Thanks.
