I have read bad things about them. Is it possible that my 360 can not read these disks at all. I think I have a pretty solid understanding of backing up the disks by swapping movie DVDs with WxRipper. Since I have been through two 10 spools, I will go step by step on how I am attempting to rip my 360 game. Find magic number...stop drive...open drive and swap movie for 360 disk and reassemble...save layout file...change line 3 to Dummy...load layout file...start dump...download SS file...use ss merger (tried all versions)...merge and create layer file...copy layer from dvd file...change iso write settings in DVD decryptor to layer brake from dvd file...burn at 4x. Disk is unreadable is the error message on my 360...tells me to clean the disk or contact XBOX support, but it appears to try to boot the disk... I guess I am convinced that the problem is my media...I have read some nasty stuff on here about the Windata R+DL files. Anyone care to confirm my theory?
