This may be what happened to others.  I was retrofitting the default tiltview index to convert it to a php file.  Every time, the player bombed.  I finally ended up pasting in code line by line and discovered what my problem was.

For whatever reason, the <base> tag prevents (in some bizarre way) the movie from loading.

Sample tag:

    <base href="" />

Hope this helps folks out!
