Bests & Worsts Reviews from Amazon

I should have read the reviews first. It seems functionality and bad discs are a common problem. I sent the first set back because the second disk locked up the machine. Had to unplug it and restart it just to get the disc out. The second set arrived and the same thing....2nd disc is messed up. Locked my machine. Not sure what to do since I do like the movies up to that point, but can't watch them all. It appears whoever produced the discs didn't know what they were doing.
