Creating a rss feed

Hi,
I made a script to create a rss feed from the Czech website stargate-online.kx.cz. The thing I want to ask for is how to add thumbnails. I get thumbnails urls, however when I add them to RSS feed using eg.

  Code:

<media:thumbnail url="http://cs505504.vkontakte.ru/u106919938/video/l_dcab4beb.jpg" type="image/jpeg"/>

, then Serviio stops showing the whole StarGate folder. So I ask for what is the right way to write thumbnails? (the current rss file may be found here).
Thanks for answer.

I think you're missing media namespace definition.

Moving this to plugin development.

Without seeing your rss code its not possible to tell you what's wrong.

Tkanks, it works now! So now if there is anyone from the Czech Rep. interested in watching Star Gate SG1 add http://radiovaticana.wz.cz/SG1-1.rss to you online resources. Note that the filename of rss depends on the SG1 serie -> eg. SG1-10.rss is the last one.

EDIT: For people fron CZ because it is spoken in Czech.
