Use DVD Decrypter http://www.dvddecrypter.com/ to copy the movie to disc as a file. Use DVD Shrink to open the Video_TS (or Video_TS.IFO file inside the folder) and shrink it as usual. DVD Shrink has difficulyt with some of the newer copy protection schemes used on new DVDs. Another possibility is the disc is dirty or damaged in some way. Here is some more from Digital Video Forums

 

ok tried all of that even tried to use dvd43free and still its this one VOB file its corrupt or sumthing. now DVD43 says this

DVD matches drive region. Use key exchange to get title key(s)

if u have any ideas please message me.

 

Did you use the newest version of DVD Decrypter (V3.5.4)? http://www.dvddecrypter.com/

 

yup used the newest version .......i really dont know what to do, and i dont know what key exchange is

 

You may be having problems with Sony's ARccOS™ copy protection system or maybe the infamous 'Dancing Boy' error. Here is a link that may help

 

I cant even get as far as to cut out unreferenced material.......it craps out in the initializing stage befor i can even customize the dvd.....
