Handbrake question?

[dmac1050]

I am ripping tv shows to use on an apple tv and iphone. I am using the settings suggested from this forum but I have one question.

the default audio track for aac + ac3 is either dolby surround or 5.1. I want to know if this makes a difference and if it does, which one should I be using to get true dolby digital surround.

thanks

5.1 is dolby digital. Dolby surround is old pro-logic.
