On March 12,2015 I ordered Star Trek: Deep Space Nine, volumes 1-7 for $130.77. A week later the package arrived(the shipping label was in Chinese to my surprise) and none of the DVD's would play. I have a Magnavox ZV457MG9, Toshiba SDV296KU, Asus BC-12B1ST Optical Drive, and Bravolink Portable DVD Player. After a week of seeing: Disc Error, Please Eject disc, Playback feature may not be available on this DVD; Windows Media Player encountered a problem while playing the file, "Unknown File"; "Read"( while the disc spun endlessly), I gave up. In my first e-mail I said, the DVD's did not work in two of my players nor my optical drive. Their reply was; What kind of players do you have? Can you test them on your computer? You may need to change the player setting to auto. If your problems continue, e-mail us a list of defective DVD's. Since none of the discs worked, I was disappointed to have had to make a list at all(but I did). Five e-mails later (they stopped responding after my third), nothing. J. P
