Thanks Steven
So - even if everything is converted as well as possible, and audio is converted without adjusting pitch, the actual speed of the final audio will be different to the original?
Sorry to be so picky here, but I need to be absolutely clear in my mind before I have to go back to the management & tell them that this just is not going to fly.

Oh, how I wish someone had mentioned this before filming. I have always known 25p cannot be used in BD discs, but was unsure that speed issues would still remain.
Not good news...........
