Netlix renting defectives?

[Graboid]

I have been a Netflix member for more than a year and have been renting mostly blu-ray discs from them. I also have been buying a lot of blu-rays for my collection. Now I don't know this for a fact but I'm starting to think that there is something fishy going on with their blu-ray rentals. What I mean is, I have had a large number of blu-ray defects from Netflix, and in all the time I have been buying I have not gotten a single defect (knock on wood) with one of my purchased discs. I would say that more than 65% of the blu-rays I get from Netflix have some kind of glitches with the picture, pixelation and hangups where I have to fast forward through them. I also have had several discs just refuse to play. Several came up with some kind of copyright infringement message. The funny thing is that when I closely examine these discs they almost never have anything wrong with them that I can see. No scratches or fingerprints or cracks--apparantly nothing wrong. Now I have no actual evidence to back this up other than my experience with their rentals, but I am starting to think that maybe Netflix is purchasing defective discs from the studios at some special rate and renting them and hoping most people won't have a problem with them. I know this may sound crazy but I can't think of any other reason for the disparity between the number of rental defects and the lack of any defects in my purchases. I've had serious glitch issues even with numerous titles that I know I am getting from them as the first viewer of the disc. I understand that the defect rate in blu-ray manufacturing is very high. Could studios be selling Netflix discs they consider to have minor defects to help cut their losses? Has anyone else had similar issues with their Netflix blu-ray rentals? Lets discuss. Maybe there is something going on here.
