Samsung Pleomax has a warehouse in Rotterdam, The Netherlands. From there the Pleomax media's are shipped to customers in Western & Eastern Europe and even to Russia. Samsung Pleomax stopped OPTO production 2 years ago and then changed to MBI mainly as of easy logistics. At the moment there are still some MBI batches in the warehouse but in a few months everything will be changed to UME. Ofcourse it may take a while till all current MBI batches are sold from the channels. For the moment you can anticipate the majority of DVD CK50 -sold into the internet channel- will be UME from now on (CD-R, DVD + DVD full printable). Internetshops are asked to change the media codes on their websites. Although the change to UME Samsung keeps the promise for quality disc with the highest compatibility possible.
