The deleted scenes are all presented in non-anamorphic widescreen format, suggesting that the entire series was shot protected for 16:9 presentation (
there's a moment on the commentary track where the cinematographer is invited to reveal what the show's technical spec's are, but the conversation moves on before he says what the intended ratio is - the show is shot in Super 16 format). To my knowledge the series has only ever been aired in 4:3 (cropped) format, even here in the UK where there's a general acceptance for 16:9 presentation on digital broadcast platforms. No doubt this will be the cause of some controversy, but in truth the widescreen clips, while making the show look a bit more cinematic, generally have nothing of any significance at the sides of the frame. The full-frame presentation makes the series a more intimate experience.
