Your question is a little vague are you saying you are trying to backup a double side disk, or that you are using a dual layer double sided disk as your media to do your burn?
The Stand is a DVD-18 format disc. I'm having trouble finding anyone who has been able to copy this. I don't care if it takes four DVD-Rs to do it but I can't find anyone who has.
In otherwords the disk is a double sided dual layer. Just rip with Decrypter and then re-author. You will have to use the start end frames in Shrink to split it up but you will lose your menus. You can download the 21 day trial version of AnyDVD and CloneDVD and use the editing features in Clone to split and keep your menus. There is a guide that covers how to do this. http://home.comcast.net/~bbmayo/1FOR1 BACKUP CLONEDVD&ANYDVD.pdf
