Sometimes you get that when there's bad data on the disk. Suggest you make an ISO of the disk and play from that. Make sure that in your image-making program you set it to [highlight]not[/highlight] skip/ignore errors, and that it retries as many times as possible.

You might also want to limit the read speed to something like 4x.

The disk can look fine on the bottom and still have problems. Label-side scratches can actually cause worse problems than bottom-side ones, as a label-side scratch almost always takes off some of the reflective layer and the data layer, leaving the disk unrecoverable.

Also, various forms of disk rot can cause an okay-looking disk to become unusable. Layer separation, data layer oxidation, reflective layer oxidation, and warping can all make a disk marginal or unreadable.

The only way to be sure is to either run the disk through a quality checking utility like the one in KProbe2 or Nero CD-DVD Speed, or try to make an ISO with error-checking left on.
