continuous date from ical feed

Hi folks,
i have set up the ical parser for drupal as described in http://drupal.org/node/341716.
Dupal receive the ics-file from an other CalDav Server and creates one node for each event as node-type event.
All these events are shown in the sidebar as list. The list shows the title of the event and the event date.
This works fine.
But i have a problem with events, which are set as repeating in the CalDav-Server.
Example: If an event is repeated by week, only the first event of the event series is shown in the list mentioned ago. Therefore, only the first date of the event series is checked by drupal. Any following events are not shown in the list.
Is there any option, which i can use to display the repeating events?
You can see what i mean, if you visit: http://www.piraten-thueringen.de .
On the right side, you will find the list with the upcoming events. You can click the event title, to see more details. On this page, you will see the field "Event Date", which becomes not updated.
Best regards and thanks for help
Hendrik
