The one problem I had with a Netflix DVD turned out to be on my side. This one disc would go screwy in exactly the same spot no matter how many replacements they sent, so I decided to pop it into my laptop. When it played fine on the computer I made the decision to replace my old DVD player with an Oppo DV-980H. No problems with Netflix DVDs since.
