Err, I'd try some additional tools.  PCM stream for DVD Video spec is hard limited to 1.5 Mb (48khz/16bit/2ch), unless this is a HD disc we're talking about - I'm not as familiar with that spec.  That's even an unreasonably high bitrate for DTS...  What does your receiver report the stream as?  Might also see what DVDDecrypter and/or VOBedit read it as.

Definitely not HD

AC3 5.1 and LPCM2

As I said, DVDfabDecrypter reports "dts PCM/2" and "Dolby Digital AC-3/5.1".

I am not familiar with VOBedit, anyway I see it shows "AC3" and "PCM" audio packs.
The PCM audio packs look like this:
