A poster over at Blu-ray.com has noticed a new problem with the DD 2.0 audio on "Encounter at Farpoint."

I just checked my discs as well and I can essentially corroborate what he's saying. The DD 2.0 track of "Encounter at Farpoint" is stereo, but no longer encoded for Dolby Surround, and thus the various Dolby Pro Logic decode settings (PL, PLII, PLIIX, etc.) do not function. "The Naked Now" is also affected, but it appears that it NEVER WAS encoded for Dolby Surround, as "The Naked Now" on my original disc one also has non-existent surround information... or at least it is incredibly faint. When I disconnect my center channel speaker, I can just barely hear sound coming from the other speakers... but I have to put my ear directly against the speaker to hear it -- so as far as I'm concerned, it's non-existent.

"Farpoint" was fine on the original disc one (except for the delay issue!)... but now it seems after trying to correct the delay issues, they caused another problem.

So again, hang onto the Next Level sampler disc, as it still contains the definitive version of the pilot.
I'm sorry but people are getting too nitpicky now. A DD2.0 track should be stereo, and you should only be using two speakers while listening to it. If the original poster wants surround sound,, he should switch to the 7.1 track.
You can label it as nitpicky -- but the fact remains that the episode had matrix-encoded sound on the 2.0 track on the Next Level sampler AND the original (first release) disc one... and now it doesn't.

"Dolby Surround/Pro Logic is based on basic matrix technology. When a Dolby Surround soundtrack is created, four channels of sound are matrix-encoded into an ordinary stereo (two channel) sound track. The centre channel is encoded by placing it equally in the left and right channels; the rear channel is encoded using phase shift techniques, typically an out of phase stereo mixdown. A Pro Logic decoder/processor "unfolds" the sound into the original 4.0 surround—left and right, center, and a single limited frequency-range (7 kHz low-pass filtered[1]) mono rear channel—while systems lacking the decoder play back the audio as standard stereo."
