Thanks Steve O for the info! Is there really a difference between "Digitally Remastered" and "Digitally Mastered"? I have seen both of those expressions used? I have always thought that "Digitally Mastered" meant that it was mastered from a film print derived from the original negative while "Digitally Remastered" meant that they used a computer to remove any imperfections from an existing film print which has been run through many a film projectors?
I see "digitally mastered" "remastered" as meaning essentially the same thing (transferring film to the digital domain). By definition all DVDs are digitally mastered.
"Restoration" is the process of returning a film to its original condition (or close to it as possible). A film can be digitally remastered but not restored. Restoration is very expensive and is typcially done for major studio releases (Fox, Warner, Paramount) and not done for the $1 DVDs, Alpha type releases.
