Everyone knows that the scene where Maddy sees blood stain on the floor doesn't include the face of Bob in the Definitive Gold Box Edition.

I've also quite a long time ago mentioned (can't find that post here) about the fact that there are some pictures which are moving instead of being freeze framed like it was at least in the version which was broadcasted in Finland (that version also included Bob's face on the carpet). For example, in the ep14 the final shot of dead Maddy was freeze framed here in Finland (and according to Youtube it's freeze framed in several other versions too) but the Gold Box version has a moving image. I noticed that most certainly the image was freeze framed becaus in the moving version it quite clearly shows how Sheryl's eyelids are moving a bit. They probably tried to hide it by freezing the picture.

Anyways, the most recent finding was the shot where Maddy sees Leland briefly turning into Bob. I don't know if this has been already mentioned here but the effect in the Gold Box version is way unfinished. The version shown in Finland (and in the versions shown on Youtube) has Leland COMPLETELY turning into Bob but this version turns Leland into Bob just from his head, upper torso and hands. The arms and legs are Leland's.

 I took a screenshot of it:

Look closely at the picture. You can even see the bottom part of Leland's jacket being a bit transparent on the right side. You can see the arms wearing Leland's gray suit and the upper torso being Bob's blue jean jacket.

Let's look at a screenshot from a version seen in Youtube:

Compare the shoulders in both pictures. Compare the bottom of the jacket. You can see the white table at the right side behind Bob but in the Gold Box version it's not seen because a partly transparent part of Leland's suit blocks it.

It is his gun he drops.  Cooper's reaction is one of the best moments in the whole series. 

The changes mentioned are no different that how it originally aired in the United States in November 1990. There wasn't a Bob face in the carpet (thank God) and Maddy's body wasn't freeze-framed. 

 Yeah, the carpet thing isn't that great although it scared me as a kid. Anyways, it seems like the episodes aired in the US were "rushed" to be able to show them on time. I'd imagine, for example, Bob's face on the carpet was supposed to be in the US version but they just didn't have the time to add the effect. One thing that, to me, confirms that the effects were rushed for the American release is the image of Bob turning back into Leland before he begins to chase Maddy. Especially compared to the European release the effect is downright horrible. It goes fast enough for most to not notice the fault in it though.

They've also done some minor edits to the European tv release. For example, when we see Bob's image in the mirror for the first time, Bob blinks his eyes just before the image cuts to the closeup of Leland in the American tv release (or at least in the Gold Box Edition and in the other set released before that) but the European tv version cuts before he blinks. That could also be seen as editing a mistake out as film editors in general sees a cut made right at the time of a blink or right after a blink a wrong way to edit.

Oh well, I guess I shouldn't look these too closely as I just noticed for the first time how the mirror "moves around" during that scene, especially when Leland turns around in the wider shot. That was unnoticeable in the old VHS recording :D I can't imagine what we may find out when we get a Blu-ray release of the series with even clearer image :D

weird, I never knew that.  I'll have to check it out.

for me, the Gold Box set is exactly how it originally aired, so naturally I wouldn't notice... but for you, I completely understand. 

I guess if they added the corrections, I would think I was watching the George Lucas edition.

Two (of many) differences I noticed when I got the Gold Box were 1) in Ep.25 when Andy imbeds his pick-axe in the cave wall, there was originally a yellow glow that lingered at the point of impact for a few seconds.  This is missing on the Gold Box.

 And 2) In Ep.27 after Cooper warns Donna, Audrey and Shelly about Windom Earle, the camera originally panned off Shelly's profile to a matted black screen for the commercial break.  On the Gold Box, the camera pans off Shelly, and we're left staring at the wall of the interrogation room!

Apparently, when mastering the DVD's, they went back to original negatives that didn't include these small effects and additions.
