How to do copy protection for DVD videos

Question

Hi. I need guidance as to how to do copy protection for a DVD (containing DVD video) such that the DVD cannot be burned in NERO and the VOB files do not get copied. What programming language to use? Can somebody help me with the coding. I am aware that 100% copy protection cannot be done as smart people can always find a way of copying it, but I am happy if the DVD cannot be burned in NERO and the VOB files cannot be copied by 85% of the common people. The DVD should play without any playability issues and should play in a PC and a DVD player.
