Knowing nothing about the show, I assume it's 4:3 center extraction from network TV. Unfortunately, when they went to digital broadcast of television, to save space I guess, the SD signal is pulled from the center of the HD. So it's like the early days of VHS without pan-and-scan all over again.
Do yourself a favor and get an HD TV if you want to talk about cinematography in general, not that they aren't still f***ed when it comes to having to frame with the center in mind. And 16:9 was supposed to fix this! Same problem, just biased in favor of the opposite aspect ratio now.
One small positive, I saw "Soldier" on Starz/Encore in HD the other day and they preserved the 2.35:1 aspect; at the same time, it is very possible the movie's poor box office numbers didn't give it a budget for a pan-and-scan for the HD telecine.
I do have a HDTV, 16:9... I'd hate to see how it looked on a 4:3 cropped TV, the people wouldn't even be on the screen.
I'll try to take a screenshot or photo of it to show what I'm talking about though.
Additionally I should mention, I'm talking about the new show on NBC.
