Dvd backup (The Prestige)

I am having problems backing up this dvd. I am using dvd decrypter, dvdshrink, and nero to burn. When I open up dvd shrink I get an error. " Invalid data in file F:\PREONNW1\VIDEO_TS\VTS_02_1.VOB" Any suggestions?

Look like it could be down to ARccOS/Ripguard protection.
