Query: They must have changed their manufacturing process

After reading all the wonderful reviews, I ordered these. Out of the first 50, four failed during verification. I'm burning at only 4x and I get absolutely no coasters when burning other brands (Sony or Verbatim). I'm very dissatisfied and I can only assume that the company has changed their manufacturing process. The media ID is TY03.Not only did I get coasters, but when the discs did work, I would find some random bad spots where pixelation in my project would appear. When I used Verbatim discs and exactly the same processing, the problems did not show up. I'm using Sony Vegas Pro 11 and DVD Architect. The problem isn't my process and it's not the DVD player, its these crappy discs! I'd give them 0 stars if I could.
