SMIL and QuickTime

I looked into SMIL/QT a couple of years back, but never did much with
it.  Could it be simply that the URL in the xmlns:qt is returning a
404?  Maybe there was a real document there before.  If that is the
problem, then maybe you can put the appropriate document up on a
webserver of your own and change the URL.

The main reason I decided not to look further into SMIL/QT was because
it was clear that (at least in that incarnation) those technologies
were being mothballed.  Maybe an QT update has changed the way things
work.  I remember isolating QT so that it could not be updated, after
I got my hand bitten before.

Hope that helps.
