There's no way they could get away with that. The tape masters for B5 look terrible! The series needs what TOS and TNG are getting. But I dunno if the original film elements even still exist.

Well if I remember the news from the time this was released on DVD, the live action footage is a new scan of the 35mm negatives, and the special effect footage (or combined live action/special effects footage) is cropped from the 4:3 tape and upscaled to 480i (and further to 576i) but it's true that was a couple of years ago.
