Languages are defined by the DVD Spec. You will find that there are far more languages spoken on this planet than exist in the DVD Spec. I’m unsure whether DVDSP makes all of the languages in the spec available to you. If you need a language that DVDSP does not have but exists in the spec, then you should be able to use DVD After Edit to fix the problem. If you need languages not in the Spec, all you can do is pick another. I once authored a series of DVDs with TV soap operas in the Urdu language, and Urdu is not one of the available language choices.
Languages in DVD work mostly for “under the hood” programming, so you can make a menu where the user can choose Simple or Traditional Chinese buttons, but you can tag them as French and Italian, for example. The experience to the viewer depends how you expose the language choices in the DVD to the viewer.
Others who have more experience with multi-language DVDs might have some elegant solutions for you.
