I just got the dvdr16sl from pcworld for £69.99 (seemed a fair price) It was to replace my liteon 811s which was a right pain and far too choosy. SO I got the philips wired in (its in an external usb box) and tried to burn some data on some infiniti dvd+r disks but It never gets to finish! always burn error. This is worse than the liteon! Is there a firmware update or something to get this working? current f/w is p1.4
