Doesn´t anyone have an idea?

Perhabs Version 6 solves the problem?

I can confirm this,
with 5.15.11 and 5.16 i have very good results except

I use the standard port 10999, Unicast protocol, Transport Stream.

Do i need any other port for communication from client to server to change the channel?

Sorry, i didn´t mention the new version.
I´ll try that and give you feedback!

Server and client both have latest version (.10).

I receive the channel list now too!
But if my client tries to change the channel, it seems the server does not receive the command to change the channel.
Is there any option i didn´t set?

I have the same problem.
Channel search worked after some tries,
and if i choose the channel running initially on the server,
i have a fine picture on the client.

But after changing the channel on the client,
the client freezes, and the server has 99% of CPU usage by the
ProgDVB process.
