I will have ALL available Laserdiscs by the end of June. I found a really nice guy on a B5 board who was willing to sell them.
For now I have a few I got off lddb and Ebay (which I'll probably sell again later), and I've done some tests with my own player (a CLD 1850). The transfers are solid, a little noisy though. I'm planing to do multiple captures later when I borrow the HLX.

The most interesting things I noticed were:

- Even this first-gen master had many of the film defects the later scan of the live-action-non-sfx footage, and there's dirt there too. They probably didn't do a wet-gate telecine or something.

- The framing as shown here

doesn't seem to be correct. The top and the bottom of the frame look as if they are exactly the same in both the 4:3 and the 16:9 versions. It's just "open-matte" to the sides. I'll try and get some screenshots up later to confirm this.

What this means is that a lot of the DVD footage could be used for a 4:3 reconstruction, it just needs some cleanup work.
