Who is it? Nobody, it's the program detecting errors on the disc.
What is it? well exactly what it states, there are read errors on the disc preventing it from being properly read before processing.
How can you fix it? well if they're actual read errors on a BD you can't. Read errors on a BD = Defective disc, exchange it.
