Trying to rip Shrek Dance Party for the kids... using Smart Ripper and DVD2AVI... no problems with functionality.

What I need help with is... Which chapter do I rip? Watching the DVD, it's chapter 21, but there is basically NO data in chapter 21 when I look at it via SmartRipper. Tried ripping ch 20, but all that contains is the end credits.

Can anyone point me to the correct chapter or location or whatever? It's for the children!!
