If it's warped, no. There's no surefire way to fix a warped disc sadly. Once it's warped, any attempts to unwarp it are almost always unsuccessful (and usually make things even more warped or worse, shatter the disc).
I've actually had good luck calling the company and getting replacements. This was especially true for the Xbox 360, as if you even bump the table its on while playing, you generally end up with scratched discs.
