hi my friend has an LG GSA-4040b drive. he has been having a lot of trouble burning dvd-r and +r. he has used mitsumi 4x, memorex 2x and 4x and it will not burn any +r media. i told him to buy princo dvdrs since i've heard they are fantastic with these drives. i also told him to flash to current firmware but he does not want to b/c he is scared it might void warrenty. if the firmware fails (just curious) what do you do to fix it? fail as in the power just shut off during update.
