You said earlier that the disk was unencrypted. Is it a disk that you made, or a disk that you purchased? I ask because I heard a while back that some DVD manufacturers would create their disks with intensionally bad sectors as a kind of copy protection. You could be running into a problem with that, if it's a manufactured disk rather than a burned disk. -- Eric Bliss systems design and integration, CreativeCow.Net -- gentoo-user@gentoo.org mailing list
