We have sent our files to Eon, now they work! Strange enough, but I think it is a good thing to contact their support-team! The only explanation I have for this is, that it is a bug that needs to be fixed! We have also explored, that vobs that were created with textures and UV-Maps looks okay in Vue 6, are unusable in Vue 7 because of a out of alignment beeing map!

I think, it is time for a bugfix.
