To followup my post above ^
Damn, this sucks. As it turns out, even though the DVD is 4.16 gig with a high bitrate, it DOESN'T HAVE 5.1 audio! What a ripoff. It only has AC3/2. My computer confirmed it. It's not a pirat*d version, it's a legit DVD. I didn't think they make DVD these days that doesn't have 5.1 audio at least.
