Unable to find cells that could be used for layer break

[chrisc_23]

Ok I know this isn't strictly an ImgBurn question but I'm getting the above error when I click on Calculate.

 

I used AVS Video Converter to create the VOB files, and I selected fit to 1 dual layer disc.

 

I don't get where I've gone wrong?

Split the disc with VobBlanker. ImgBurn shoud be telling you what cell to split. Guide on site.
