The first thing to be aware of if you are thinking about Copy Protection on your disc is that no copy protection hardware or system is 100% reliable. If an experienced hacker or computer expert wants to get into your disc they will. Saying that, there are several methods available that will stop the average guy in the street from copying your material.If you are going to get your discs REPLICATED the copy protection needs to be put in place at the authoring stage. Then make sure that the replication house you are using is aware of this nad they will finalise the operation at the stamping process. With regard to cost, there is usually an extra one off cost from the stamping house then a licence cost per disc, not a great deal approx between 1 – 5 pence a unit depending on quantity.Up until recently is was very expensive and quite difficult to get copy protection on DVD discs in quantities less than 1000 (replicated) but nowadays with modern equipment and software any quantity can be protected and does not cost the earth. Most people are aware of duplication towers. The single towers allow you to duplicate upto 10 or 11 discs at a time. Well now there are towers available that if specific specialised software is used they will copy and protect discs. Basically this software embeds a proprietory copy protection encryption into the master DVD video through a PC. This can then be transferred onto the duplicators hard drive via the USB connection. A licence has to be purchased for each title but then you can copy protect as many discs as you require without any additional costs. Additional licenses are available on a USB in quantities from 30 to 100. The actual towers are slightly more expensive than standard towers but obviously their costs will decrease significantly as time goes on.
