Hi, a few searches for this subject led me to this thread/forum.

I ordered a few pre-Lowry laserdiscs, I'll see how they compare.

The Jungle Book Blu-ray is the same restoration as the 2007 DVD (I'm sure there are a few minor tweaks but I no longer have the old disc for reference). The DNR'd line work doesn't hold up as well in 1080p compared to its non-Xerox based predecessors, soft shots are especially deteriorated. Color timing seems to be okay and doesn't have any glaring consequences because the film had flat lighting to begin with.

I'll post my thoughts on the 1992 laserdisc when it arrives.
