BE CAREFUL with LG drives!!!! There were problems that using DVD-RAM discs in LG Drives did something to the disc that caused them to no longer be compatible with Panasonic DVD burners.
The thought was it only happened on CPRM-enabled discs (copy protection.. most newer DVD RAM are CPRM) and the LG did something the Panasonic didn't like and locked the disc from future use.
(I should add, I have indeed verified this problem with my own equipment. I just quit using the DVD-RAMs from the Panasonic in the LG and didn't do any further tweaking/testing.. and I have a stack of RAMs for the computer, and a stack for the Panasonic)
Do some Google searches before buying and using an LG drive. You might want to just try to find a DVD-ROM drive (like a Toshiba or something) that can *read* DVD-RAM (but won't write) and then do your editing and burn using a different drive. Alternatively, you could pick up a Panasonic DVD-RAM drive but they unfortunately are not very good all around DVD burners.
(don't get me wrong, most LG drives are quite good but not in this case)
