The Scientist video link on Vevo, is the same duration as the ColdplayTV The Scientist video. Both of the videos are 4:26 minutes long.
Perhaps Vevo is trying to upload all of Coldplay's old video, since they only have Christmas Lights up there.
Vevo has been known to screw up Coldplay's videos before, which is why I and a couple of my other friends got to see Christmas Lights about 6 hours before it came out. But of course, Vevo realized that and decided to block it. :D
