Can you open device options in ProgDVB and set "use demux"?

Or in ProgDVB.ini
[BDA]
DemuxRequest=1

- no tagged pics, PLEASE. Use links instead -, it isn´t possible and not to find in the ini.

What means: "UI Crashes"? Comes when I click on a channel.

You can install ProgDVB in portable mode for ProgDVB.ini in root of application. Or look ProgDVB.ini all disk. Because path depended from installer settings.

Of course I found the Prog.ini, but not the Demux-Entry in the ini. And there is also none int the program itselves.

You can add
[BDA]
DemuxRequest=1
to this file in notepad.

So, I reinstalled my complete system on a new drive and in that prcess together with windows 10.
No it works with the latest version.
But the problem I had isn´t solved. Everything you wrote and I tried didn´t work, also not the last demux entry.
And this can´t be.
I was quiet close to delete ProgDVB and wanted to installed another program like DVB-Dream where everything worked, but now it´s ok.
But I have to say: thank you for your help, although the essentially problem isn´t solved.
