first off its from the Warner Archive Collection not Warner Home
Video proper so there's no scene selection. plus when Curtis is
talking to the board of the motor car company his voice is quite
low. something must have gone wrong in the transfer of the audio
tracks.
As far as the sound, I played the same scene with and without my 5.1 systems hooked up. It sounds to low as sent to my TV but quite normal with my 5.1 hooked up.
Chapters do exist but as you said no Menu item for Scene Selection.
I noticed his voice dip in that scene as well.
It's a hell of a good start though. I finally have my favorite movie on blu-ray, I can forgive the omitting of the scene selection feature.
And Ms. Natalie Wood in her camisole on blu-ray... Wha-ha! More than makes up for it.
