Do any of Slysoft's products have the function of adding custom menus to re-authored DVDs?

I own AnyDVD and will soon be purchasing CloneDVD, and I'd like to be able to add custom menus to re-authored DVDs.

I'm very new to all this, but I have read on line that when adding menus, it is important that the DVD files, which the menus are being added to, are not reprocessed, as this degrades the quality. Does this make sense and is it possible using one of Slysoft's products?

I run Windows 7 64.
