I had problems in the past with some Neflix DVDs that my Pioneer Elite 59AVi, didn't seem to like. Cleaning them made things better or eliminated the problems. Over the past year my BDP-83 has not had problems with Netflix DVDs or Bluray disks, although I think I had to clean one because it was skipping.

I have on occasion received a broken disk, or one with obvious bad scratches, but the breakage may have happened in shipping. After I reported the problem online they sent another the next day.
