SHW-160P6S have problem with dvd-r burning

Ok this is how it does
my liteon SHW-160P6S used to brun to dvd-r are before and now it not bruning to dvd-r
this is wht i found out due to test
My drive will read all media inclue cd and DVD it will read all dvd-r and dvd+r all cd
it will burn not burn dvd-r anymore, but it will burn to all over dvd( dvd+r dvd+rw those are the one i tried) it wllburn to all cd

My drive alwayz useto burn ti dvd-r a week now it has not been burning to dvd-r
i have tired downgrading the firmware and upgrading it back up the lastest firmware on liteon website
it didn;t change anythinki still can;t burn to dvd-r
i have tired putting the drive in another computer i get the same results
i have tired using diffrent burning programs all the same results still can;t burn to dvd-r
I notice when i am using nero in the log it don’t set the booktype i notice whn ever i burn to dvd+r you can see it set the booktype ( i can’t remmber if before when the drive used to burn to dvd-r if it used to set booktype)
When i try to burn to dvd-r durning the burning it gives an error, i can’t remmber wht exactly the error was
but i now that the dvd-r don’t look like if any data was written on it after it gives me the error
when i try to read back the disc the drive light just stays on and it show up as no media is in the dvdrom
the other think is when i insert a blank media before i burn to it the dvd rom reconize the disk but when i try adn burn to it it comes back with and error and after tht i can’t use the disc back it just don’t read the disk any more

PLZ NOTE
that i have tired diffrent pc
diffrent operating system
diffrent burning programs
I GET ALL THE SAME RESULT
i have tired reflashing with same result ( i use the window flasher to flash for liteon)

I was thinking do u think i should do a direct flash to drive in DOS with the bin file from codeguy

PLZ i would really liek to relsolve this problem
I also read somethink about cross drive flashing i don;t now much about that but was wonderin would tht help

THERE is a log that i just got from nero
i have tried using verbatim dvd i get the saem error
