I appear to have successfully installed media9. My first attempt to use it (listed below) has led to an error, of course: in this case a complaint that 'car' is not a known option. Is it impossible to use spaces in the file name of the media? This would be a serious problem for me, since all my hundreds of file names have spaces in them - usually lots of spaces! (I added quotes to the file name, but that didn't help.)
\documentclass{article}
\usepackage{media9}
\begin{document}
\includemedia[
width=0.4\linewidth,
height=0.3\linewidth,
addresource="D:Audio/67/67A1_Snippets/67_321 fast, car, go here fast.mov",
activate=onclick,
deactivate=onclick,
flashvars={source="D:Audio/67/67A1_Snippets/67_321 fast, car, go here fast.mov"},
]{}{VPlayer.swf}
/end{document}
P.S. All my media files are MOVs, but I believe they are MPEG-4 inside.
