Would it be possible for someone to further clean up the video, particularly the animated segments? I mean isn't animation easier to restore than live action? I'm just thinking about the cleanup that was done for Grave of the Fireflies by Central Park Media. They used DVNR and it the before/after shots were impressive although I noticed smearing in a few scenes like there was with the Star Wars THX versions.
By the way, the Sing A Long Songs dvd "Pongo and Perdita" has Zip-A-Dee-Doo-Dah on it. I know it's considered bad to use varying quality levels for a film presentation but I still think it could help. Someone did mention the song sounded off so that could be used for comparison.
