This is an LG forum, but your topic looks more about standalone hardware and video editing software.
This forum is more oriented towards PC DVD recording hardware. Isn't LG DR4810 a standalone DVD recorder? Using a standalone DVD recorder is a lot different from using a PC DVD recorder.
Finding out what firmware a PC DVD drive is using is easier. Just running almost any popular burning or testing software can provide the information. The DR4810 package should have a bundled manual and it should also include the information for finding out and updating the firmware in DR4810.
I don't think Samsung DVD-RW media are good enough for your great DVD recorder.
