I haven't seen all the extras yet. The first is the same as the one that aired with the show, there is a new second one and then some Smeg Ups (or is it Outs), and deleted content. The whole second disc is extras.

The Lister sneeze-ironing is only trimmed in that before he starts talking about tomatoes he tosses it in the air only once (instead of twice), and one line of Rimmer's rant afterwards about him planning it is trimmed.

The cuts are subtle and seem pointless. When Cat goes on about being caught by the giant testicle he original complaint about his clothes and hair being ruined. In the new cut only his clothes.

I could understand cutting some of the mugging of the camera or really useless jokes, but that's not really how it came out (in my opinion).

Since most people seem to agree it was needed, I don't know why they didn't dub in a laugh track. Mind you I don't usually like having them tell me when to laugh, it's just that the show feels really sterile and quiet (the CG making that worse).
