dashboard demo does not load music or video

[d~l]

I can't get any music or video clips to play in the Laszlo dashboard demo app (on Laszlo web site).

And where are the music / video clip sources defined in the app source?

Music and video clips are now working in dashboard demo .. must have been a glitch yesterday.

I've narrowed down the problem in running the dashboard media play demo here ..

music and video play O.K. in IE 6.0, Mozilla and Firefox .. but, for some reason, music and video in this demo do not play in Opera 7.5.4

any particular mime types / file extensions I should check in Opera 7.5.4 preferences?

They don't play in Konq. either.
