The censored lines are described differently HERE - can someone confirm, and correct the description if necessary?
Are there any video differences? Are you planning on a VHS/LD to DVD transfer, or just capturing and syncing the audio for muxing with the DVD (keeping in mind this announcement).
Little Mermaid:
I did read a thread about someone working on a restored version, but if the DVD release that was pulled is actually the original theatrical version, then why is a preservation neccesary? Surely this DVD can be tracked down on eBay/Amazon Marketplace or whatever.
Song of the South:
I have this version which is 29.97fps and hard-telecined. Unfortunately the BBC broadcast was also interlaced, apparantly due to a botched NTSC to PAL conversion. Doctor M tried the Avisynth filter "restore24" on it, but I think he gave up in the end. Might be worth trying the newer "R_pack" restore function on it to see if it fares any better.
