Query: Terrible DVD quality

It's a good season in terms of program content, but the quality of the DVD's is inexcusable. I returned the first set because the episodes on disk two were completely unwatchable. If the disk would load at all, it would only play the first half of the first episode, then it would freeze. It would load the first episode, and sometimes you could fast forward through this episode to get to subsequent episodes, but it would play about 5 seconds of them (blurred and skipping) before it froze and stopped. I tried playing this disk on 3 different DVD players, and all were varying shades of intolerable. So, I returned the disks, got a replacement and it was the same, the second disk was useless. Both sets were new, never opened. There are only 3 disks, so one third of them are worthless straight out of the package. Returned for refund. Will not order again.
