I, too, am a big fan of SD--and I have the DVD video release of 2vN, as well as the CD. I wasn't aware that there would be much difference in the audio tracks (I admit I'm not really up on the latest audio technologies that I suppose are geared to the "home theater" environment).
I first heard Steely Dan when I was about 15, when they had "Reelin' In The Years" and "Do It Again" out on radio! When I was a teen growing up in Birmingham, Alabama, there was a local FM station that played what we then called "underground" music--where I got to hear a lot of the ProgRock stuff that I enjoy today. Anyway, they often played entire LP sides, and I first heard "Countdown to Ecstasy" that way. Even though I hadn't heard it in years, when I bought the CD reissue of CtE, I was amazed at how well I remembered "Boddhisatva".
Just some off-topic meanderings. I MUST be getting old.
