Cooliris and the crossdomain file

[#1]

I'm trying to get the Cooliris Flash app to display photos hosted on my site following the instructions here: http://www.cooliris.com/developer/documentation/?p=embed
I can get the app to display the default stream from Flickr just fine but when I try to have it display an RSS feed of my own, it refuses & says that I need to put a crossdomain.xml file in the root of my web site.
Well, I have put the crossdomain.xml file in the root (http://www.emcorp.force9.co.uk/crossdomain.xml) but it still won't fly.
Should the crossdomain file just work (ie is this actually a Cooliris problem), or do I have to get PlusNet to change a setting on my account to enable crossdomain?
[Moderator's note by Thomas (Be3G): thread moved to a more appropriate board.]

I'll assume that's a Communitywide shrug of the shoulders then 
Is there no-one from Plusnet on the forum who knows if the crossdomain.xml file should work on a Force9 web site?

If you've used the crossdomain.xml file given at http://www.cooliris.com/developer/reference/media-rss/ it should just work.

OK thanks Gabe, that eliminates that then. I have used the crossdomain file exactly as supplied.
I'll tinker a bit longer but I think this must be a problem with Cooliris itself. Web searches indicate plenty of other people are having similar trouble.

Just as a quick test, you could try a mymedia.xml file like:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
      <rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/"
      xmlns:atom="http://www.w3.org/2005/Atom">
      <channel>
          <item>
               <title>My Image</title>
               <media:description> It works.</media:description>
               <link>image.jpg</link>
               <media:thumbnail url="http://www.username.force9.co.uk/folder/image.jpg"/>
               <media:content url="http://www.username.force9.co.uk/folder/image.jpg"/>
          </item>
      </channel>
      </rss>

and use the cooliris builder at http://www.cooliris.com/yoursite/express/builder/ clicking on Media RSS and pasting http://ccgi.username.force9.co.uk/folder/mymedia.xml into the Feed URL box. The select grab embed code at stage 3 and paste the code into a .html document. It seems to work.

Very useful pointers, thanks again Gabe.
You know what? I just got it working... typical cos I've been fiddling with it for a couple of weeks, on and off. Turned out to be a single coding error in the embedding HTML. My fault, but the error message about the crossdomain file was a complete red herring. Anyhow, I apologise to Cooliris for suggesting it was their fault!
Thanks for taking an interest. Much appreciated!
