D56A slimtype to LiteOn SOSW-852S?

Hello all. I have got recently a recurring problem with my Sony D56A slimtype that doesnt recognize new media that i am buying (DVD-/+R) example Memorex DVD-R 16x. I already have the last firmware available PFS3. I went recently to Liteon webpage and found they have a new firmare for LiteOn SOSW-852S from 2006 that is more recent than PFS3. But that scrambled so i cant extract it. The solutions that i can think of is changing the Sony to Liteon with unscrambled or instead inserting the Memorex 16x data in PFS3. Since i am a newbie in this matters would anyone help me to find the better way?


Edit: This is how is recognized the Memorex 16x

Drive Type = DVD DUAL
Disc Type = DVD-R (Single Layer)
Disc MID = 52 49 54 45 4B 46 (RITEKF)
Disc TID = 31 00 00 00 00 00 (1…)
Nominal Capacity = 4.38GB
Manufacturer Maybe = RiTEK Corporation
SMART-BURN Speed Limit = 2.0X (Write)

When i try to buy one it fails always.

Learning my way i was able to descramble and use that Liteon, unfortunatly it didnt help, so i think i have no other option than try to inser Memorex 16x data on it. Can anyone point me to what i should read to learn?
