He explicitly wanted none of his materials to be used without consent. Too many dirty hands in South Korean web space. (I just provide web server/FTP account and some HDD space for his own site.)
He does work for a Lite-On IT distributor as I mentioned before but his test results are highly reliable.
Though there are not that many DVD media recordable at over 5.5MB/s (which is about 4x DVD speed), he couldn't find any media at all that does. If there's any LG GSA-4081B for sale anywhere outside Japan and South Korea, I can just say not yet, unless it costs the same as ND-1300A and LDW-4x1S.
I don't think the guys at Samsung and LG are that dumb but I know they always have serious organization problems. They don't work at all when they feel some redudance or lack of power in their organizations.
