Using my laptop built in drive (I have a DELL XPS M1330) which I believe is a Matshita UJ-857G I am unable to burn any DL at all. I have tried using several brands of disc namely Verbatim, Aone and Memorex also various types of software including Clone CD and Nero.
I also have an external Lite On SOSW-852SX (firmware PSX3), I have tried all of the above with this drive also however I am able to burn to Verbatim's only.
I take it the problem could be down to the firmware of either of the drives in order to burn to more media however I cant find an update for the matshita anywhere and the Lite On has the latest official firmware.
Does anyone know where I can find updated firmware either for the matshita or the Lite On.
I have the same machine and the same Burner. After a long research I suspect that Dell is limiting the Dual Layer capability in certain areas or countries, where they sell the machines at lower price or special offers. So they do not need to change the hardware, just the bios or the firmware. That is why you will find this burner as a DL in all the listing, but in dell part and spares deparment. In summary, it is a trick of dell. You, (and I) will never burn DL in this machine-burner. We will never find a firmware, nor even the spare part. And Dell will never, never speak.
May be installing Windows 7 will undo the trick
