Bug Description

I set VLC to play a AVCHD Blu-ray-disk with menues created on 40 episodes. If it should have done it right, it should have displayed the menues with options for choosing a film to play.
It could not cope and hot down. The disk was UNENCRYPTED and made according to all rules.

Could you try to reproduce it with the latest PPA? It should be solved.
