Try new prerelease https://www.progdvb.com/download_progdvb.html

Put this file to Transponders folder. I am not test this case every day but must work.

I am back all changes and public "d" version. Still crash?

I am found 2 channels in my collection with black screen in OpenMAX on nvidia box. Try use FFmpeg mode for all channels (Options->Playback)

please try free version of prerelease. Is it working also?

Please try new prerelease https://www.progdvb.com/download_progdv ... lease.html

No. This is not fix but search direction for me.
Please test every Engine and report what engine is crash

One idea. Please try https://www.progdvb.com/download_progdv ... lease.html

But channel type if h264 without ac3?

What format? Please send me sample of list.

Crash after open of any channel or after 3-5 minutes?

OK. I am like test total same case. Do you use OpenMAX in playback options of ProgTV?

What you mean Hardware setup? You must select Stream reader in TV Sources of ProgDVB. Of course need x86 version of ProgDVB.

Try install last ProgTV+ from my site and test

Do you mean crash in x64? StreamReader does it better. API for blind scanning is not official and has complexities for different TBS devices
