I must say that Netflix handled this problem with a defective Tartuffe very well. Immediately upon reporting the disc as damaged, they fired off a replacement, which I'd requested. I hadn't received it after 5 days, so I reported it lost. That very day, I received it. I went ahead and watched and returned it. However, they have a second replacement already on the way (which will arrive Monday), which I wish I could cancel. Meanwhile, they've received the "lost" one. Even though I've had the same movie shipped to me again unnecessarily, I appreciate the effort.
It was worth getting the replacement disc, because I enjoyed the second track, which was a documentary called "The Way To Murnau". Very informative.
In six months and 95 discs, my only other problems have been with the mislabelled Last of the Mohicans and a defective copy of The Passion Of Ayn Rand. I should write them to let them know they should add "The Way To Murnau" to the DVD description. Someone might want to rent it for that feature.
