I think it is an old v4 vob that needs a convertion. There is a converter on the CD for this i think - i am not sure wether it still is there. Unfortunaltely it does not work very well so be careful and don't destroy your original. One way is to find a Vue 4 installation, load it in there and save it again. That might work.
