In most cases a CD player will reject CD's for the same reason: The CD isn't reading the disk. That could be from the wrong file type of the data written on the disk which your CD player wasn't designed to play, the lack of a TOC (table of contents) or the disk wasn't closed when it was burned on a computer, providing a TOC.
The other possible causes could be scratches on the disk to heavy for the laser to get a lock, the laser itself not focusing or you've put the disk into the CD player upside down (labels up).
