Urgent: Backup a DVD of a Dvd backed up by Intervideo DvdCopy Platinum 1.2 or 2.0 ?'

Is it possible to backup an DVD that has already been backed up by Intervideo Dvd Copy Platinum 1.2 or 2.0 ?

it should be like making a direct copy of any other dvd.

Thanx, it works now, to increase speed actually select immediately the video_ts folder on the backed up dvd disc.
