I am trying to burn onto Asda DVD-R discs with Convertxtodvd and it says it's the wrong type of disc, but i also try with Maxwell DVD+R and it says the same. Can someone tell me where i am going wrong ? x
Try getting a lense cleaner like Wak suggested, then try burning a file onto a DVDRW disc. If that fails then most likely the DVD drive is faulty then I would look at buying a USB external DVD drive.
