Jump to Main Menu/Jump to Movie problem

Using AnyDVD the jump to main movie button works fine, in that the movie starts as the first play item, skipping all the adverts etc, but the jump to main menu doesn’t appear to do anything. By that I mean I still get the adverts and warnings etc before the menu is displayed.

My testing isn’t that extensive, as I’ve only tried it on 2 movies so far, SpiderMan 2 and Garfield the Movie. Garfield has given me other problems too, see this thread in the CloneDVD forum for details, so there may be something else going on there too.
