Panasonic TX-P42GT30B view streaming

I have a some of problems:
1. I am trying to get live streaming from my Samsung R530 laptop to my Panny. I have the console configured for Coolsport and have put the groovy plugin into the plugin directory. In the library section I have selected live streamimg and put http://www.coolsport.tv/stream3.html in the box, I've tried some other addresses but they both give the red x and fail to display on my menu on TV. What do I need to put in the URL box?
2. I have got audio from my laptop to the TV OK. When I try and get, for e.g. videos I put the video directory in the path but none of the videos(which are in their own directories) appear. The same with photos.
3.Am I able to show my laptop desktop, e.g web browsing on my TV?

OK I now have Coolsport appearing on my TV under Video/Online but it is empty, there are no streams appearing as they do on the web page. I have done this by entering http://www.coolsport.tv/schedule.html in the URL and switching the type to 'Web resource'. If I switch it to 'stream' it disappears from the TV.

Ask at the plugin's topic, you might get more help from the developer there.

Thanks, I did contact the developer directly and received a less than helpful reply, I'll try what you suggest.
