Oh my God. I cannot believe this went out on TV to children... I used to watch that when I was a nipper...
In all seriousness, it's obviously edited. Even allowing for a time lapse between video and audio, some of the dialogue doesn't match the mouth motions in several scenes. Phew!
Edit: Just saw Alan's post on the GIMP, noting his comment that, "Much to my annoyance the GIMP makes little effort to clone the Adobe Photoshop user interface or any [other] well known interface".
To adapt a well known phrase, one man's annoyance is another man's joy. I dig the GIMP's interface which can be a joy to use with a decent WM. (Sadly Metacity lacks a few telling tools which may explain your frustration.) I absolutely abhorred the Photoshop interface after having not used it (in favour of el GIMP!) for a few years. I found editting multiple images at the same time in Photoshop 6 (not tried 7) to be very difficult and slow.
And v2 of the GIMP really is an incredibly nice tool to use in my very humble opinion.
I think ultimately it comes down to liking what you're familiar with. Something unfamiliar almost always feels unwieldy, especially when you're trying to accomplish a similar task for which you are already set in your ways with doing.
