I liked the SitS old HDTV version, but at didn't find it to have a LOT of detail above the DVD. It does have the edge though.
Was 20k Leagues damaged by restoration? I hadn't heard that.
Is the Aladdin HDTV prior to the Imax/Lowry changes?
I assume Black Cauldron is likely to be pretty similar to the DVD because there hasn't been a restoration IIRC.
Never seen an Aristocats HDTV version. There have been a lot of bad versions of that film.
