Dear All,
I would like to be able to embed movies in a latex presentation (i.e. to play a movie within a pdf file). This should be doable if I look at

and in particular at

However, despite generating the pdf myself and following the steps described in the link above, when I open the resulting pdf file movie.pdf, acrobat reader complains about some missing player needed to play the movie, but I have just uploaded flashplayer this morning...
I am puzzled and do not know what is going wrong. I am running ubuntu 10.04 on a amd64 architecture.
Anyone else experiencing the same problems?
Any suggestion is appreciated.
