If you are using some unbranded medias then this problem is common

but for good brands this should not be the case

I have 2 lg DVD writers (i.e. GSA 4120B & GSA H10A).My Regions on both units (both on the same computer)are both set on '0'.Is it possible to make at least one of the units "REGION FREE" ?Thanks

for burning dvd try using a program SlySoft AnyDVD for veiwing try vlc media player. VLC is one of the free software and open source DVD players that ignores DVD region coding on RPC-1 firmware drives, making it a region free player. However, it does not do the same on RPC-2 firmware drives. If both are RPC-2 then you might have to try a program like DVD Region-Free 1.0

My disk drive doesn't detect burning media.

You MUST have software that is for burning a CD.

Some examples are "CD Creator", "Nero" and others.

These programs are OFTEN not included and MUST be purchased seperately.

HL-DT-ST-DVD-RWGRA-4120B cannot burn

Drive might be dead. Try another drive to eliminate the drive as being the problem. Also try DeepBurn writer software.
