NP. There's really nothing that can be done about it when working with a source that has DVNR. DrDre's script does improve the quality of the source, but it can't remove that. Someone with more technical knowledge than I could tell you if the DVNR is applied directly from the T/C machine or if it was added by a secondary process, but either way it's in the source. For some of the movie it doesn't create considerable problems, but in some scenes it creates considerable drawbacks. For a 1993 T/C it's not all bad, it probably wasn't cutting edge, but it was what it was. :)

Today we want better, of course. Even the 2004 DVD was made in a T/C and not a film scanner as I've mentioned elsewhere. DrDre's work, however, is very valuable. It's given me a way to improve my own upscale of the SD elements in The Phantom Menace.
