I don't understand this. The CD already includes Reed-Solomon codes for error correction. Sucking up more space on the disc with a second helping of Reed-Solomon codes shouldn't do anything other than reduce the amount of usable disc space. Especially since PARs are usually ~20% of the original data. <br>

In the future, you might want to include par2 files with the data. This isn't<br>
foolproof, but it has helped me to recover 2 failing DVDs that were not<br>
completely gone.<br>
