Earlier I decided to watch Gladiator. I got this disc when it first came out for Christmas & I've watched it a couple of times before with no problem. About half way through it starts pixelating & the picture & sound cutting in & out for the rest of the movie. This also happened right at the first with the Dreamworks logo right after the audio selection screen. I took the disk out & it has no scratches, just some light cloudy areas. I guess my question is...what do you do when something like this happens? I'm extremely fussy about how I handle & store my DVDs. Is there any way to return it to Dreamworks? This is the first problem I've had with any DVD. Thanks for any help on this.
