I have a problem whereby my new dual layer dvd burner wont burn the blancs dual layer dvdrs i have just bought. I tried to put an avi compilation together on a dual layer disc. At first the dvd drive did not recognise the disc, eventually it tried to burn for a short time and then failed. I also tried to burn an iso image and again it wouldnt work. I have updated with the latest firm ware, but still no luck. The pc is high spec and less than 6 months old. My dvd drive is a LITE-ON LH-18A1P. The discs that failed were bulqpaq blancs. If anyone has experienced this problem and has any advice it will be much appreciated. Normal 4gb discs work fine.
