Difference between 811s and 812s

Hi all,
I tried to search the forum but couldn’t find it. What is the HW difference between these two models? I would love to know if the difference is only in firmware or are there other important add-ons in 812s.

The 812S has a different chipset then the 8_1S series of burners. It also has a different PUH (pickup head) then the 811S.
The 851S uses the same pickup head as the 812S.

The 812S has at least the same MT1816E/MT1818E chipset as the 811. Check this http://homepage2.nifty.com/yss/sohw812s/jouhou_812s2.jpg image of the japanese 812S review linked here http://club.cdfreaks.com/showthread.php?threadid=90415.

Hrmmm after further investigation is appears you may be correct. There was other information from a reliable source I had read that said otherwise. But after looking into it further is appears we are mistaken.

Ssseth,

Well that means the chipset is NOT going to be same as the that of the 832s - Dual layer drive.
Which would mean no likely hood of a firmware upgrade of 812s to 832s Dual layer. Am i correct ??

If that is the case - i see no benefits in buying the LiteOn 812s over NEC2500/Pioneer107 as a DVDWriter. SHame

:confused:

832s? where do i find more info about it?
tks
