Re: DVD not working - did dmesg - can anybody tell me what this means?

Try wiping the dirt of the disc. If that doesnt help try another dvd, does it open? If not could be a faulty drive or PATA/SATA cable. The error msg's means the drive cant read form the disc.

Thank you, the drive was the problem, not the disc. Shiny new one going in this evening!
