Those later 90's era DTS versions must be very nice, but it's still unknown as to how to transfer the stream off of the LD.

Thanks also to this forum, I learned to capture DTS soundtracks from laserdiscs... for now, I can capture the whole DTS audio only, without video, as if I try to capture audio AND video with VirtualDub, the DTS becomes totally unusable after some seconds... but this is still good, as the few seconds in sync at the beginning of each laserdisc side capture is useful to sync the DTS audio only track.

Those are only early tests; hope to start a restoration project with a DTS laserdisc title soon.
