The easiest way to copy it is to use either CloneDVD 2 or DVD X Copy Xpress. You can get a trial version of CloneDVD 2 that lasts 21 days from this website http://www.slysoft.com/en/download.html. CloneDVD 2 is good but DVD X Copy Xpress is better, but the trial for DVD X Copy only copies about 1 GB of the DVD.
Hope this helps if not, send a reply!!!
