They remastered the original Star Trek (with William Shatner!) in HD. It still has the bars left/right as if SD. But the picture quality is clearly HD. http://www.tv.com/shows/the-wire/forums/is-the-wire-filmed-in-hd-169-why-43-dvds-5252-1133700/
Dominic West probably hoping this gives his acting career a shot in the arm. I gave up on him after Punisher: Warzone.
I would think the actual conversion to HD wouldn't take very long. For the star trek episodes, they spent a lot of time on the audio and special effects, which made it pretty expensive.
