[NTG-context] can not include movie

[Michail Vidiassov]

Dear All,

ConTeXt user manual says movies are just like figures,
but when I process

\starttext
\placefigure[here]{none}{\externalfigure[demo.mov][width=0.7\textwidth, height=.7\textwidth, label=demo, preview=yes]}
\stoptext

with

context filename.tex

using the latest minimals without any custom settings
I do not get movie included.

What can be wrong?
I am a ConTeXt newbie and fail to see any possible place for errors in the 
above test case.

        Sincerely, Michail
