I've had three DVD's recently that rip normally with DVD Decrypter,file mode-no warnings pop-up. But when I try to compress them with DVD2ONE it stops half way thru the disk. I tried DVD95Copy,DVD Shrink,and CloneDVD with the same results. Some programs stop,some say they completed but in all cases I wind up with about 2.3GB's instead of 4.37GB's. The disks were The Sopranos,Are You Being Served,and MASH.
I re-ripped with Smartripper and to my surprise I got a normal comprssion with all four compression programs.
I'm guessing that it's a layer change glitch in DVD Decypter???????
