No, I don't believe if I understand you correctly, these files which play incorrectly are now on a cd and on your mobile device then there is no way to fix them. BUT if the files DO play correctly on the CD and what you want is for them to play correctly on the computer then delete the ones on the computer and download the ones from the cd to the computer. But as I said, if you burned the disk and they are bad then there is no way to correct that.
