I have a TDK 440N multi-format DVD - is a rebadged NEC 1300A. Could it be possible to put NEC firmware on it - or would this firmware just be the same as TDK's? I am having issues with it doing PS2 back-ups!!
Here is where you want to go for TDK firmware. you cannot put the nec firmware on your drive but they have plenty of other options here for you. http://www.herrie.org/modules.php?name=Downloads&d_op=viewdownload&cid=4#cat
