‘Twas my understanding that principle photography from TNG, DS9, and Voyager were all shot on 35mm film, but they were compiled and edited in 480i standard definition video. Perhaps more importantly than that, all special effects were rendered in 480i standard definition video as well.
If that’s the case, then to get TNG, DS9, or Voyager in HD, one would have to go back to the original source footage (the film) and it would have to be re-edited, while the effects would have to be re-rendered from scratch. Not an impossible task (if they go the CGI route for FX), but Paramount may not do it if they don't believe it would be cost effective.
You are correct, and every time one of these posts gets started, somebody has to step up and explain it again. I'm glad it was you this time, not me.
