Adding Menus to existing .vob files

Hello, I have five movies converted to .vob files on my hard-drive and now want to go back and add text menus to those files so that each individual movie can be easily accessible. I understand how to do this using ConvertX2DvD, but when I look at the folder I only see four .vob files. It seems that two of the five films have been merged into one .vob file. I know that five movies are there because I loaded five .avi files into the program and I’ve watched the DVD that those files were burned to.

Here is a pic of the folder containing the converted files…

Now, either I’m going nuts :disagree: or this is just part of the normal processing of the program?

Without full log there can only be guessing.
