Before I write this message, I made a search and couldn’t find any answers about my problem. That’s why I am looking for your opinions.
I am not a newbie, so I’ll give enough info about this situation. My LG GSA-4163B DVD writer has never written any DVD faster than 4x up today. But I always blamed the cheap DVD media about this problem. Never suspect the dvd writer. Yesterday I finished my rubbish dvd medias, and buy a pack of Memorex DVD-R (100 dvd). These are brand new medias and support up to 16x write. When I come home and tried, I faced the same again that bloody 4x limitation.
So I made a little research and find DVD Identifier software then identify these media as CMC MAG. AM3.
Unique Disc Identifier : [DVD-R:CMC MAG. AM3]
Disc & Book Type : [DVD-R] - [DVD-R]
Manufacturer Name : [CMC Magnetics Corp.]
Manufacturer ID : [CMC MAG. AM3]
Blank Disc Capacity : [2,298,496 Sectors = 4.71 GB (4.38 GiB)]

And to wipe the questions out of my mind about dvd writer’s firmware version, I upgraded to ver. 106 (the latest). Later on I find another software named MediaCodeSpeedEdit. This was a very useful software that you can have a look at a list that which media with what speed will be used after using that firmware version.
So I loaded ver 106 firmware file to this software and then look for CMC MAG. AM3 inside. Unfortunately can’t find CMC MAG. AM3 definition inside GSA-4163B ver 106 firmware file.
Only these ones as DVD-R
CMC MAG 2x, 1x
CMC MAG. AE1 8x, 4x
CMC MAG. AF1 4x, 2x
And these ones as DVD+R
CMC MAG E01-000 8x, 4x
CMC MAG F01-000 4x, 2.4x
CMC MAG M01-000 16x, 12x, 8x ,4x
CMC MAG R01-000 2.4x
So, here is my question!!!
This dvd writer (GSA-4163B) is capable of writing 16x at DVD-R when required media is available. And also this CMC MAG. AM3 (Memorex 16x) is also capable of 16x write by the proper dvd writer and firmware. So what the hell is going on here??? Is there any way to write at 16x speed on these medias by this dvd writer?
PS1: Also as a last solution by using MediaCodeSpeedEdit, I import CMC MAG. AM3 media code block to the ver 106 firmware and form my very own custom firmware. Again the result doesn’t change… So I stuck and need help…
PS2: Thanks for your answers…
