As Rotary rightly said unless you've got the proper set up, receiver and speakers to process DTS signals, then get rid of that, applies to any film.
5.1 Channel AC3/Dolby is usually the main audio stream/dialogue in any movie these days, so always keep that ticked.
The 2 Channel AC3 could be downmixed version of the main stream for "stereo" setups, or it could be the directory's commentary (voice overs) as these are usually encoded at lower quality.
Try playing that stream on your PC and see what it is exactly.
Set up DVDFab HD Decrypter to automatically select English-Dolby Digital, and whatever subtitles you want(if you want any), and you are set.Easy bam-burn!
