Hey Kenshin, need your help

Hi Kenshin, you seem to know alot about LG and thier products so I was wondering if you can help me.
I have used a few LG DVD-R discs (coded LGE04) and It has LG down as the manufacturer of the discs. Do you know if these are made by LG or some other manufacturer? I know LG used to get their media made by BeAll but it has changed. LG also have discs codes LGE08 and LGE16.
Are you able to tell me if LG have a DVD production line or not for thier discs?
Many thanks
