Hi.  Simple RSS is working on my Joomla site and pulls in content from rss feeds including Yahoo pipes.  Display the feed in Firefox or Yahoo Pipes and it's sorted out fine by time order, display it in Simple RSS and it's jumbled up.  One of the feeds is this one from Ebay, sorted in time remaining on the auction:

pipes.yahoo.com/pipes/pipe.info?_id=ZPw62emk3BGpF46inkartA

If it helps I had the same problem with Slick RSS, another Joomla plugin based on SimplePie.

Any ideas anyone?
