Just picked up a couple of movies from the rental store. However, they look as though people played with them as frisbees. On the inner ring of both discs (the little hole), there are numerous cracks and some chunks of plastic are even missing. The cracks don't extend very far out into the data portion of the disc, but I am a little concerned with what they might do to the player. No sense risking a 200 dollar DVD player for a 6 dollar rental, right? I'm sure others who watch rental DVDs have gotten something similar. What did you do? Do you think there's any risk to the player by using these discs?
