Hello, i have a LG GH30n and i wanted to know is it possible for me to change the midia type to dvd-rom, if so is there software or firmware that i use to do this?
Your drive is no DVD-ROM, so this subforum is wrong.
I'll move it to the correct subforum.
What you mean is the booktype of either DVD+R or DVD+R DL media. Bitsetting is the verbal description.
First use Imgburn, nero cd dvd speed or dvdinfopro and check the drive capabilities.
Then, without posting the current firmware on your drive, you cannot expect any answer to your question.
