You too fast Yes, this files good for test on my side.

Please, check again the changes from 7.14.6 to 7.15.0. For me the problem is there.

Prog, any news for this problem?
I can delete the files from my web server?

I get files but still not test. btw, what I can do for repeat problem? Step by step please.

I don't know.
Open ProgDVB, play one channel, change channel... Close ProgDVB. Open again ProgDVB, play one channel, play another channel... Close ProgDVB. Open ProgDVB and look for problems with channel list, or check random channels.

P.S.: "BNT World" from my last screenshot here is missing in channel list now. I don't have any idea why. This channel on the server exist.

What source of TV on server? Do you update list on server?

The source of the server is TBS 6618 - DVB-C. The channel list is updated automatically, but I tried manually and nothing changed.
If today work fine, may be tomorrow I will have problems.

And I can't understand you. Why you search the problem in the server? Server 7.21.1 with client 7.14.6 work very very very fine. The problem is in client, not in the server.

Client not gen new channels. It take it from server. Try reimport channels on clieant in Channel list->Search.
Do you have channels on "losted" tab?

OK, but I don't have any problem with 7.14.6 in client side. After this version I have this problem.

I know for this problem from 7.15.0 but never report this bug here. This is my mistake, sorry. I am dev too.

No, I dont't have any channel into 'lost channels' tab.

Why this bug is in client side? Because on port 10999 on the server the channel list is correct. If I use VLC with ASX(or M3U) file all channels playing without any problem. Or may be the bug is on list.bin file from the server for the client?! I don't know. This is binary file and I can't see the content.

But please describe steps for repeat this problem on your files.

Nothing to explain.
Open the program and look. If all is OK then close and reopen the program and... if all is OK close and reopen the program... and again...

Another example : I clicked on "Nova TV", but I watched "Diema TV"

Temporally solution : Remove channels and recreate channel list.

Today same problem with "Nova TV" and "Diema TV". I has clicked on "Nova TV" but watched "Diema TV"...

ProgDVB 7.21.02 has been installed on the server and on the client side.
The channel list on the server has been recreated(Remove channels and Scanning again). The channel list on the client has been recreated too.
I will check for changes.

"БНТ 1" has been renamed a "Nova TV"...
