I heard that the new special effects done for the Director's Edition DVD were only made at standard resolution, and so the film can't be released as-is on Blu-Ray. Does this mean they will have to redo the effects all over again for a Blu-Ray release (or to air the film in HD)? 
(This is the same reason why TNG, DS9 and Voyager must be redone from scratch if they are ever to be aired in HD or released on Blu-Ray, since all of their effects and editing were done on videotape which has a very low resolution.)
