RSS / XML feeds don't display in published swf

[brainSalad]

Hello,
For my class' final project, I created a little eBay search tool platform. It
1) performs a search (and the link generates affiliate coding so commissions would result if an eBay affiliate used this application on their website),
2) it shows a few eBay-related news feeds, and
3) it shows some beginner's videos showing how to buy on eBay.

Playing the swf as a movie on the desktop, within Flash, works fine.
However, since I've published the swf into a webpage, the search function and one of the RSS feeds do not work. My application is at:

http://dongarber.com/flashassets/eBayTool.html

I've read about crossdomain policy issues, but I'm stumped about that. Using FireBug, I see an error message:
"NetworkError: 404 Not Found - http://blog.auctionbytes.com/crossdomain.xml"
This is the domain where I'm calling the RSS feed. Because this domain does NOT have a crossdomain.xml policy in place, does that mean that no matter what I do, I'll never be able to draw from it? I've set up a crossdomain.xml file in my website's root and it consists solely of:

<cross-domain-policy>
<allow-access-from domain="www.dongarber.com"/>
<allow-access-from domain="dongarber.com"/>
</cross-domain-policy>

And, the URL I use to connect to eBay's api is:

"http://rss.api.ebay.com/ws/rssapi?FeedName=SearchResults&dfsp=32&from=R6&nojs pr=y&output=RSS20&saaff=afepn&siteId=0&afepn=53358 27058&customid=flashfinalprojectRSSFeed&satitle="+searchTermBox.text+"&saprclo="+minAmt.text+"&saprchi="+maxAmt.text+"&fbfmt=1&sabfmts=0&sascs=0&fsop=33&fsoo=2";

This works when I cut and paste a sample URL into the browser, say, when I substitute a search term minAmt and maxAmt into that gobbledegook. The search never returns anything when this app lives on a published html page...

What can I do?

This would be a cool addition to my portfolio, if I can get it working online...

Thanks guys.

From adobe community boards:
"if you can't upload files to the rss server, you can use php on your server to read the rss and use loadvars (as2) or the urlloader (as3) to retrieve the xml from the php."

Ugh. Gotta learn how to incorporate php into AS3 to display XML...
