Clone DVD2 Copying help

I have a llitle sctrached DVD.

I was able to copy VTS_01_1.VOB - VTS_01_4.VOB plus other files to my hard drive. I was unable to copy VTS_01_5VOB and VTS_01_6.VOB becuase of the damaged dvd.

When I open the file using the Clone dvd2, I am able to see the movie. I would like to use the chapter cut and make the movie for the length I have vob files for.

When I try to copy the vob files it freeses. I think it searches for the missing files I have. Any one can help me on this.

I have used shrink and dvd decryptor but no help.
