No RSS Feed (same in MySQL dbase)

A relased a little new project on web and i used wordpress again. All works great (again) but only the rss feed strikes.

What make me confused is, that i cant find any information about an rss feed in my mysql db. In my older installation on another db i find the table “weblog_rss” & “weblog_links” and on my first page the rss feed works great. But this twice documents are didn’t exists in my new db (there are named all “wp_name”). I have made a dump of all wp_data in MySQL, delete them and reinstall wordpress. The same… no one rss in MySQL. Whats up??? What i made wrong???
Ore there are changes after the last Relase of wordpress? (my first wordpress i upgraded from 1.5.1 to 1.5.2, on my seccond wordpress blog i directly installed 1.5.2.). Who i can look for mistakes?

The domains are in german, but when you will take a look…

My problematic RSS/ATOM page: http://www.mysterydakota.de (RSS feeds are on the left site)
Working RSS,/ATOM Page: http://www.com-2-mac.de (RSS feeds are on the right side)

Thanks for help…
