Cool thing about the 4K restoration on Blu Ray
Originally, show creator Shawn Ryan was against releasing the show in 16:9 format, but this was overidden by Sony for the DVD releases. Part of the reason for Ryan's objection was that, although the show was shot in 16:9, it was always done with 4:3 in mind. So, when the 4:3 image was uncropped back to 16:9, there were many instances of crew/equipment on the sides of the frame that Sony just left there for the DVD releases. Part of the remaster process for the Blu Ray included specifically reframing shots where crew/equipment were in the 16:9 frame and removing them.

I cannot say with 100% certainty that every instance of this has been corrected. But all the instances I knew about have been fixed on the Blu Ray. This is probably why Shawn Ryan approves of this 16:9 release while he opposed it on the DVD release.
Pretty cool that this attention to detail was put into the restoration.
