Display a DVD

[Niakwé]

Everybody know flash gordon? No? So, I explain it's a professionaly recorded DVD. Video codec is mpgv
subtitles codec is spu
Audio codec is a52
So, I thought it will be fun to watch it but... the audio sounds terrible... However, VLC already get this audio codec...
Antoher remark : when I launch the movie without the DVD menu interface the sound it's ok. there is a problem when i watch trough the menu.

Your turn to give explanations!
