I used a USB SPDIF in/out box so there was no mixing, and I got a bit-perfect digital rip of the AC3 audio stored on the Laserdisc. It sometimes took a couple of goes when the soundcard skipped a beat in the middle of a recording, but otherwise all I had to do was strip out the padding between AC3 frames.

There are no laserdisc players that can play AC3 out via S/PDIF. Only the digital audio (PCM) tracks are available via S/PDIF from the player. For AC3, you must use a demodulator, because the signal from the player is (analog?) RF. The demodulated AC3 signal can then be captured via S/PDIF, but it still needs the stripping, as mentioned.
I first captured the AC3 from the 1997 SE in about 2002. I can't believe it's this long later, and I still haven't really done anything with it!
And yeah, I did the capture for 'The Frighteners'.
