I'm thinking you mean the blu-ray player setting. I popped the Aviator blu-ray and DVD into the panny and nothing about audio came up in the menu.

YO!!!
Isn't this fun!!! Sure is for a DumDum like me.
Argh. You are new to this aren't you.

I mean the "languages" or "audio" menus that come up every time you insert a BluRay or DVD. That's why I was specific and called it "the movie's audio setup menu".

We've already discussed that the Aviator has no hi-rez audio, so languages likely gives you just a choice for Dolby Digital, and then in a couple languages. Anyway....most other BD discs will, indeed, have a choice. They will likely look like:
English TrueHD 5.1 24/96
English Dolby Digital 5.1
French Dolby Digital 5.1....yadayada. Usually the one on top is the highest resolution audio, the best. Look for the ones called TrueHD, DTS HD Master Audio (called DTS HD MA) or Lossless PCM. That is all I meant!
