Running Video of MyBook World II on WD Live TV Hub different then just running off the Hub itself?

I’m trying to move all my Movies onto my MyBook World II and then run them off my WD Live TV Hub. When I have the movies on the Live TV Hub I just click “enter” on the folder of the movie I want to see and it runs fine, including the DVD menus. But when I run the movies off the MyBook World II I have to hit enter on the Video_TS folder and then it just runs the vob files in order, which doesn’t include the DVD menu. Why do I have control when the Movie Folders are on the Hub but not when I run the same Movie Folders off the MyBook World II?
