../../wp-rss.php?cat=19 still shows feedburner rss for whole site

howdy, here’s my problem:

I’m using the excellent Eventcalendar plugin. I want to allow my readers to specifically subscribe only to my ‘events’ category (since this is the category calendar entries fall under).

• I want to use Feedburner’s service to do this. Feedburner already provides feed services for my whole site’s RSS.
• However, when i use my browser to query the url “../wp-rss2.php?cat=19” (the events category) it results in a page featuring my site’s complete feed instead of the feed for just that category, displaying the URL of my Feedburner feed (http://feeds.feedburner.com/BasketballExchange)
• A second method is to enter the URL mentioned on EventCalendar’s Advanced Queries Page this way:
  http://blog.address/wp-rss.php?ec3_days=7 but it still results in same.

My questions:

What did I screw up on my blog for this to happen?
Does it have anything to do with the category to tag converter? I implemented it, so does querying ../../index.php?cat=19 not result in anything anymore?
Please guide me.

Many thanks in advance
