Hi,
I had the Klack-TV channel configured for AvantGo.
I had to do this on the Klack-site, not in AvantGo.
After switching to Isilo, using the same Url, I see all channels. Do I have to do the configuration again?

Alex, this is pretty easy, just do this step by step:

When you go to Klack's main page with Internet Explorer, you have to login (left side, "anmelden").

Once logged in, you can customize for your favorite tv stations.

Now have a look at your cookies (either in your cookie directory when you are using IE, or with "Privacy->Cookies->Manage Stored Cookies" when you are using Mozilla -- I prefer Mozilla when I am dealing with cookies).

Klack.de creates one cookie called COOK_USER with a digit value, e.g. "13214". This is your user id. Write it down.

Now open iSiloX and find the Klack TV+ entry. Right click -> Properties -> Cookies. There, double click on the COOK_USER entry. Here, replace the entry for "Value" with your own user id. Then click on OK->OK and make sure that you save your changes with File->Save.
