It was just part of the Bangladesh piece.
huh? don't get it .... I guess I'll have to go and look again. I just watched the whole piece and didn't notice any further links.
getting old and stupid I guess...
Yep, I see. I assumed "Back" and "Next" referred to the main menu titles. Yes, I'm dense, but at the same time, speaking as A User Experience Design Professional (ahem), I'd say that ii a touch ambiguous.... normally this sort of menu item on a DVD is labelled "Extras"
...actually, it is all a bit skewed now I look closely. Go to the "green" screen. Click "back" - you get the "red screen". Click "next", you get to the "blue screen" related to the red screen, rather than the green screen again - you'd generally expect "back" and "next" to be reversible. And the difference between the "red screen" and the "green screen" finally is not so clear.
Having said this, most DVD menus are an absolute pig's ear. I've never tried to build one myself - maybe there are some inherent limitations. Or maybe movie makers are not so good at interactive design :-) Or maybe that white Merlot I just helped to empty was even better than I thought.
