No, you need an actual blu-ray drive or writer to be able to use them in a PC. A regular DVD drive won’t do it. Also, the opening sequence would only count as one scene, even with multiple shots in it.
You are probably right in saying that the article is speaking of 15 minutes and not 15 scenes. This site http://www.commeaucinema.com/dvd=93891.html suggests that the Bluray actually has 41 minutes of deleted scenes compared to the DVDs 15.
Ok, I’m going to attempt a list of stuff that was deleted/truncated in the movie. This won’t necessarily reflect the blu-ray since I don’t actually know which ones are on it (other than the ones that are also on the DVD):
1/ the opening funeral
2/ It’s storming and Gunnar’s wife is telling a ghost story when the son is sent outside to tie up the horses. Lights in the trees lure him into the forest…
3/ Kainan’s captain is alive after the crash – they have a conversation in the morning before he dies.
4/ A much longer version of the scene with Rothgar and Wulfric in the tower (atop sheild hall)
5/The first moorwen attack was longer with more action. People were on fire and there was even a stampede of people that run over Kainan.
6/ The baby moorwen’s birth was longer (and effects were complete)
7/On the bear hunt, Wulfric finds a piece of Kainan’s space ship and is confused by it.
8/When no one is looking (during the bear hunt) Kainan sneeks a look at his beacon to see if anyone is coming for him
8/On the hunt they come to an offering tree where the Vikings put offerings on a stone for the forest gods. Rothgar makes Kainan make an offering even though Kainan thinks it’s silly.
10/ During the trap building sequence Gunnar goes to look for his men and finds the head of one of them on the offering stone.
11 There’s a bunch of stuff filmed for the herot hall/sheild dance scene that was trimmed out
12 The scene with Kainan and Freya at the well was longer
13/ Not sure if this was shot or not… there was a scene between Freya and Wulfric where he shows he’s jealous about Kainan’s moving in on his territory.
14/ There was scene between Kainan and Rothgar after the trap is built that was pretty much trimmed to one line of dialoge
15/ The flashback sequence was longer. Since the captain is dead at the start of the film, his parts are trimmed flashback sequences as well.
16/ At the part where Wulfric throws Kainan a spear they had some reconciliatory dialogue there that was cut
17/ Rothgar’s death scene
18/ Wulric comes out to the people after the death scene and they indicate that they don’t really accept his as king.
19/ Extended under water sequence – Kainan goes down to the ship and swims around inside and finds the metal, but bumps into something and has a scare when he sees that it’s a human face, and we see all the coffins floating in the water. He loses all his air and has to go up to an air pocket and get air. He comes back down and gets his metal and on the way out, that’s when he sees the baby.
20/ After swimming to shore Kainan checks his beacon and his people *are* coming for him. Wulfric is mesmerized by the technology…
21/ The moorwen’s splash at the end (effects were complete but cut to meet the contractual running time
There’s probably more but that’s what I can come up with at the moment. There were also a couple scenes that were planned but never shot.
