Query: Defective

I strongly recommend that you NOT spend your money on this DVD. The entire second disk that I received is defective. It is clearly a problem with the disk itself, entire parts of the content are inaccessible and the problem always occurs towards the end of program sections. After reading reviews of later seasons of Northern Exposure, I see that this is a known issue.Northern Exposure is great...that's why I bough the DVD. Amazon is very convenient...that's why I give them hundreds of dollars a year. But this product is defective.
