As suspected, it's not as easy as recording the encoded DTS stream from SPDIF as PCM.
At this point, I've recorded the DTS track in various resolutions and rates and tried running the resulting PCM/WAV files through BeSplit 0.9b8. With each file, BeSplit hangs when trying to handle as DTS.
I've also tried playing the encoded stream directly to my receiver, even starting a DTS encoded stream for the header input and then using a Toslink switch to toggle to the already playing PCM/WAV with DTS "noise." Nothing.
After some more digging, I've found a single post in a thread on the doom9 forum which hints that only certain sound cards can handle a DTS input stream. My MacBook's SPDIF-in can't do this and my Asus Xonar Essence STX most likely can't either, but I do have an Auzentech card lying around somewhere, so I will try this card sometime soon. If that doesn't work, I'll buy the Prodigy 7.1 HiFi, noted in the post:
i am able to record DTS using a Prodigy 7.1 HiFi soundcard with a Toslink connected directly from laserdisc player (have an Audigy2ZS but it doesn't have a digital input). Under the card's Config, selected EXT and it automatically detected the Toslink connection. Set to 44100
Recorded a 16-bit 44100 stereo wav in Cool Edit Pro 2.1, and it recorded great. Saved as a Windows PCM Wave, ran the wave through BeSliced using BeSplit 0.9 beta 8 and it created a .dts file that worked - older builds didn't.

Used eac3to to extract wavs, used Cool Edit Pro to cut out silence, etc. down to the millisecond and resample all wavs to 48000, then DTS Suite to make DTS-HD MA file (didn't want to go from lossy to lossy, so I have "lossless" of "lossy")
