Why does my Sony dvd player flash error "C:13:00?"?

I have surfed a couple of internet forums discussing this same problem and many have stated it was due to a dirty or scratched disc.

The movie disc had no visible or obvious scratches on it. I did clean it with warm water and soap using a paper towel. It still wouldn’t play. It still gave the error.

Anyone have any ideas what this error could be?

All of my other dvds play just fine.

By the way, this was a movie from Netflix. All other movies from them have played just fine so far, just this disc gave me problems.
