Most of Star Trek will NEVER be in Hi-Def!
The ONLY Star Trek series that can be released in Hi Def is the ORIGINAL SERIES. That show was shot and finished on film. It won't be widescreen, but the masters are on film so hi def resolution is supported.However, Next Gen, DS9, Voyager and most of Enterprise was SHOT on film, but edited and finished on NTSC VIDEO (in fact TNG was the first show ever to do this). That means the master tapes for these shows are all 525 line video and they will never look better than they do on DVD. It is physically impossible to release them in hi-def.Enterprise switched over to 16:9, but it was not actually finished in hi def until late in the game.The movies can all be hi def, except for (sadly) the new edition of ST: The Motion Picture. The special edition director's cut was only finished on NTSC and can never be upscaled to HDTV. Only the original theatrical version can be re-scanned to a higher resolution.Use this info to plan your purchases accordingly!
