RSS Syndication - really strange behaviour

Wednesday 29 April 2009 1:58:24 am

Hi there,

I've big problems with my RSS Feed. The content is syndicated quite well, but every client (RSS Reader) reacts in another (wrong) way.

<b>Some example:</b>
- Slim RSS Reader: All news are up-to-date and shown as they should be -> OK
- FeedDaemon: No News are shown (but also no error message)
- Newsgator: No News are shown (but also no error message)
- Google Feed Reader: Only "old" articles are in the feed (very strange)

But the syntax of the feed looks fine, the W3C feed valiator check is passed without any errors.

Here is are some lines of the RSS Source:
