Yes better wait until a newer firmware for 832S is out with better burning results...

I have LiteOn 451S is there any chance, I could transform it into DL burner? Will there be any other firmware patches?

Not impossible. But pretty unlikely... but it's still early, as DL media isn't out. The possibility or impossibility of this might become more clear by the time media comes out...

Hmm, looking at my documents i saw that:

-451S is based at SANYO DB10S OPU and MT1816/1818 Chipset
-812S/832S are based at SANYO DB10S OPU and MT1816B/1818 chipset

Since the chipset is different possibly you cannot upgrade it

I wonder, I have a LiteOn 811S, how different is it from the 812S, and I wonder if it is possible to flash it to support dl media. Btw emperor, your last post says both have the same chipsets

811S uses Sanyo DB10SA and MT1816/1818 chipset...so probably won't work. As for the 451S/812S they use different chipsets so...also won't work!

401S chipset: MT1816E/MT1818E
411S/811S chipset: MT1816E/MT1818E
451S/851S chipset: MT1816E/MT1818E
812S/832S chipset: MT1816E/MT1818E
1213S chipset: finally, first LiteOn-made DVD-writer *not* to have the MT1816E/MT1818E

The chipset has not changed since the 401S, and the 401S and 832S actually share identical chipsets. This is why if you flash a 832S firmware only a 401S, the drive will still be recognized by the system, the tray will still work, lights will still blink etc. What is preventing the crossflash is not the chipset, but the other hardware components. Which is why if you flash a 401S with a 832S, you won't even be able to read a CD, much less burn a DVD (and because the chipset is identical, the drive isn't "dead", and all of the drive's basic functions like reading/writing firmware were still intact, so it was very easy to flash back, without needing to use mtkflash). Having the OPU model number is not enough, as there are a number of other important hardware components, too, such as analog filters, motors, signal processors, etc.

The 401S/411S/811S family is simply too far removed from the 8x2S family in terms of hardware for a crossflash to be possible... the 451S/851S is actually very closely related to the 8x2S family. They're actually closer to the 8x2S family than they are to the 11S family. This is evidenced by how single-layer burning worked (except for 8x -R... the drive will fail at the 4x->6x upshift point) with the older 812S firmwares like UYS1 or US05 loaded onto a 451S. This 51S@812S crossflash only worked (partially, of course, as 8x -R wasn't there) with the very early 812S revisions; it completely stopped working with the newer ones.

code65536, as usual, impressed me with your deep explanation of the various LiteOn lines, so the question now is, the 451S can be transformed to a 832S DL recorder?

So far, the people who have been brave enough to try this have found that 451S@832S will read just fine (in fact, before this transformation, the 451S had trouble reading DL media, which was resolved by loading VS01), but unfortunately, it will not burn at all, making it pretty useless and pointless to even try.

code65536, thanks for your test report, so right now, users should keep their eyes on the 812S->832S conversion...

I've read that you can now officially flash your 812S to be a dual burner.

http://www.liteonit.com/ODD/English/e_downloads/e_firmware_dvd%20rw.asp?Flag=1&Item=DR8US0N&Model=SHOW-812S

What do you guys think??

Danhill dual burner mean DUAL FORMAT burner not DUAL LAYER burner...... this DR8US0N is for SHOW-812s and not for SOHW-832s

Ohh I see, so this is just a regular update to the firmware. Thanks for the heads up.

Lets say I do upgrade to this new firmware, can I in the future upgrade to the 832 firmware to make my DVD burn in dual layer??

yeah ..... you can but first must patch 832s bios to recognize 812s burner ;o))) ... go here and read carefully http://codeguys.rpc1.org/
