Have you ever bought a blockbuster movie from a store (legitimate store) and it has been a copy that has been made on DVD-R? No – and you never would! This would have been produced using DVD duplication but the professionally produced copy you buy is produced using DVD replication. Is there a big difference? Well yes, several.
When you duplicate or “burn” a DVD (just as you would in your home computer) there are many variables that can produce a disc that does not work. The data when copying is buffered and then burnt to the blank disc at whatever write speed set by the user and this method produces errors on the disc and sometimes the disc itself will contain bad sectors. It is a method which can be unpredictable which is why duplicated DVDs can NEVER be classed as retail ready product. Even if they are packaged in the same way as those in the stores!
Replicated DVDs are created using a master impression of the data which therefore means every single copy is identical to the original and can therefore be sure to work! It really is as simple a comparison as that – for retail ready product you need to use DVD replication services rather than DVD duplication services and if any company or person tries to convince you the duplicated DVDs they could provide for you are retail ready then do not believe them.
DVD duplication can provide the best solution but the key thing to be sure of if you want professional product on retail shelves, DVD replication is the only method to use.
