Ben,
first of all – there´s something weard with your project.
I´ve seen 100GB BD-ROM-content, while you not selected any BD-ROM-content. the disc is MORE than full. that might be the first issue.
2ndly to use WAV-audio is no good choice, well it works better with BD but it is a big mess with DVD. 95% of all DVD-player-issues I´ve ever seen came from uncompressed PCM-audio.
your menu seams to be ok, so far as your screen-grab showed, but in detail this could only be verified when looking at it in detail.
teamviewer would be a good way to do so.
cheers
