I have a Hewlett Packard pc and suddenly the CD/DVD writer is only able to burn cd's an 3-4 times speed, instead of the 40 times it usually manages. I have tried closing down all unrelated programes but this doesn't make any difference. DVDs are taking over 2 hours to burn instead of the 15 mins usual time. I noticed that this has happened since using the Lightscribe feature on the drive, but I can't see how this would be the cause. Please help!
