No. This is not fix but search direction for me.

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

Are you sure in last version of ProgTV? This bug fixed 1-2 version ago.

Понял. Сейчас опубликую новую версию.

I need numbers of zips. What engines good and what bad.

Do you test engines in my previous post? What engines crash?

btw, you can try modern version of StreamReader.dll from this site https://sourceforge.net/projects/crazyscan

Do you mean normal scanner or blind scan mode? Do you try BDA.device in place of StreamReader?
