download for OS X 10.4.1?

I recently downloaded a .smil file from the NPR website.  Not knowing what
this was, I did a google site and found more information than I could fully
digest on your Ambulant player, source code, etc.  I am not a developer, or
really very technical....just a user who likes to try the new technologies.
I use OS X 10.4.1, and tried to download your 1.4.1 player, but hung up with
a message at the bottom saying, "Fetching image
http://images.sourceforge.net/prdownloads/internap_137-54_2.jpg"

While I don't understand much of what I read on your site, I did see that
you are working with OS X 10.3.  Does this mean that you are not yet
compatible with OS X 10.4.1?

I will appreciate any help you are able to provide....and good luck with
your project....it sounds interesting, and I am looking forward to being
able to use your player.

Thank you,
Bill Slate
