No fix I am afraid but have suffered the same problem after using Tesco DVD+RW disks in my daewoo dvd recorder for ages - now new disks only appear to record for 10-15 mins before 'disc error' appears and then have to switch off at mains to reset dvd recorder. Nothing has recorded. Have also purchased dvds from other retailer in case Tesco had a faulty batch.
