I have some Memorex and Fujifilm DVD+R media. Both have a Ricoh media code. But, the serial numbers look a lot like those on Ritek CD-Rs. I have seen that Ritek DVD+Rs have a Ricoh media code. And Memorex and Fuji have both used Ritek before for media. Didn't Ritek make CD-Rs for Ricoh once? This all makes me think that Ritek is making DVD+Rs with Ricoh's media code. Is this true?
