Thanks for posting this. As you mentioned, some ringing and other original video artifacts are more visible now but that's a good thing. I didn't know these got the transform decoder treatment, but I guess it makes sense. I'm guessing Jonathan Wood drove most/all of the restoration process. I knew he'd worked on several different series but I didn't make the connection until a few days ago that he'd left the BBC and works for Network now. Everything he's worked on has been done really well; he sets the bar pretty high.
