The aim here is to get a very simple wired movie, which might be generated automatically, to talk to a vanilla m3u file, something I poached from mp3.com.
The Quicktime movie above should be able to talk to the m3u file below.
For a while it worked locally, but not from my server because of a MIME configuration. Now I have fixed it so it works without me having to change anything on the server!
I just had to use the type="video/quicktime" attribute in the embed tag.
The Quicktime movie above has with wired actions embedded into a text track.
Try downloading an archive of the relevant files and seeing how it works for you.
The archive also contains the LiveStage project for the wired movie, if you're interested in that.
