I can't watch the video at work, but have you found the tonic, or root note?
Try humming or playing along with it, using single notes, until you think you've found the base of the scale. You should notice a strong desire to resolve back to that note if you try to go up or down one interval in the scale.
Once you find that, if you can't hear the mode by ear (major/minor, or other mode) then you can try filling in the scale bit by bit (just use your ears for what sounds right), then write down the whole and half scale intervals (as in, W-W-H-W-W-W-H) and then figure out the mode from there.
That's my usual method if I can't pick it out aurally.
