Blu-Ray menus & chapters grayed out

I made an ISO of a Blu-Ray with AnyDVD 6.4.6.2 & it plays fine with the exception of the root menus & go to chapters options being grayed out & inassessable, while the movie is playing there is no way to go back to the root menu w/o stopping & starting the Blu-ray from the beginning. The next & previous chapter tab does work though as does all the menu & sub-menu buttons . This limitation is the same Using Power DVD 8 & Nero Showtime 4.
Any ideas on how this could be resolved?
