Thanks for your reply, Ken.
When in Video Studio I click on (3)Share and Create Disk, it invokes the DVD Movie Factory. In DVD Movie Factory, the first screen is Create Video Disk. I don't see a box with Create Menu next to it anywhere in that screen. The next screen is Menu Editing, and again, there is no box in that screen either. I tried to delete the Background and annoying standard soundtrack, but it would not let me.
This is DVD Movie Factory 2010 version 22.214.171.124 that came with the trial version of the Video Studio Pro X3.
I have the old buggy DVD Movie Factory 3.0 and there is not problem removing menus there. I may have to go back to the old version
