SH-S182M read-write problem

Hello.
I am new at here. I’ve used the search for looking solution to my problem but i couldnt find anything.

I have SH-S182M, i can’t write a CD or DVD.
Exact model: “TSSTcorp CD/DVDW SH-S182M”
My region is 2 (Turkey)

Also, when i try to playback a DVD movie, its stucks frame by frame. DVD sound too. I hope you got what i mean.

I used to have S00 firmware, i’ve updated to S06 but i have still same problem.
Can anyone help me?

Sorry for my poor English.
Thanks!

check of your drive is in udma2 mode first, from what you say it sound like pio-mode.

Hey,

How can i check that?
My 1st IDE channel = UDMA5
2nd IDE channel = UDMA2

I checked that in Device Manager.
