The pre-defined "seed" mux list for 19.2E is more than likely out of date. Try manually adding a live mux from here or match your working receiver.

Thanks for that hint, I have already tried several muxes I found on a different satellite info site.

I will try some more from Lyngsat later today.

Another question: Where and how can I set the DiSEqC mode, as in the image tv-astra.jpg?

I guess that's also necessary... Probably it's preset to 1/4 that's why it all works fine with Hotbird but not Astra...?

I have no idea how a monoblock LNB works, so keep in mind that what I tell you may be wrong...

I think you have to change the configuration of your satellite from 'Universal LNB only' to enable the switching between the 2 networks (depending on the number of connections on your diseqc switch)

I also have a DVSky S960 and i have connected it to a diseqc switch with 4 ports. 3 of them are used to connect to an LNB. These are just single LNBs, pointing to Astra 1, Astra 2 and Astra 3 respectively.

So, in the satellite config I have selected "4-Port switch (universal LNB)".

Once you do that, you can assign the different networks to the positions on the diseqc switch

I have added the diseqc and lnb position to the network names - just to make it easier for myself.

Hello Gert,

thank you for your answer.

Meanwhile I got it working with the settings visible in the attachment.
