Hey hercules! DVD shrink rips your dvds into multiple sections because your HD is formatted in FAT32. The max file size is like 1Gb. I ran into this with my old comp... it blew before I figured it out. If you format to NTFS it will rip the movie as one complete file.
BTW, I backup my movies with DVD shrink as an ISO and when I want to burn I use nero. You never know when label side damage will happen. If that happens, you are fudged.
