It gives me always the first sattelite (astra) no matter how I set the
DISEQC value.

But won't the first vlc incarnation grab the card and make the second one
fail to grab the card?

I've read through all this several times and still find it very confusing.

But with vlm the client will need to first connect and activate the channel
before it can connect to the stream?

Hmmm, I thought what I want is a very common thing.  But now you made me
very uncertain.  So let me explain what I'd like to have:

I have a dish with 4 LNB's connected to a 17->4 diseqc switch.  The
diseqc outputs are connected to four DVB-S cards in a single PC.  Now
I would like to be able to watch different programs from different
rooms (cellar, loft, sitting-room, sanctum).  The client should be
able to choose the channel with something as simple as
"mplayer http://server:1234/CNN" or some such.

BTW: Actually, what I'm searching for can basically be done with VDR's
     streamdev plugin.  But since VDR is designed as a standalone
     application, there are stability problems: when one client fails
     to keep up with the stream, vdr restarts and quits connections to
     all served clients :-(

     This is why I decided to try vls/vlc because they are basically
     designed for streaming and should not quit everything when one
     client has problems.

     An other advantage of the vls/vlc solution is that I could buy
     the existing set-top-boxes so I don't need to have a PC in every
     room.
