Okay so I haven't watched it yet but I will confirm that the criticisms above are accurate. The scene with Gurney Yueh & Hawat entering has the door opening twice (before any of them come through) and then the scene repeats itself first with voice over and then without - it is very poorly edited for sure in that scene. This isn't the only time this happens either - in the beggining the lady from the Theatrical edit starts explaining the history - you know all this stuff:

"the most precious substance in the universe is the spice milange. The spice extends life. The spice expands conciousness. The spice is vital to space travel. ... The spice exists on only one planet in the entire universe - a desolate dry planet with vast deserts. ... The planet is Arrakis - also know as Dune."

Then the male narrator says the same thing word-for-word with pictures. I'm serious, it's just the Greedo-Han-Jabba information in SW except longer and even more directly one following the other!

The scene with the big alien creature in the glass container near the beginning has terrible quality audio editing also. You can clearly hear the difference between the theatrical and the extended versions - Spicediver's edit is much more seamless around areas of the film where he edits things together from different sources.

First Giedi Prime is depicted as red in on picture and then green in another. The "Book 1 ... 3" titles he added fell outside the 2.31:1 picture ratio. The criticisms on facebook that the video is stuttery is also true as it's 29.97fps.

And considering his (in my view fair) criticisms of Spicediver's cut it was silly of him to leave David Lynch's name in the credits.

I don't think I have the patience to watch this edit all the way through.
