Problem:
I was using ProgDVB 6.46.06 successfully with my hardware. Now I have updated to 6.49.06 and ProgDVB is always crashing with following Windows message:

Problemereignisname: APPCRASH

I reinstalled the whole Applikation but with the same error result. After the ProgDVB GUI can be seen, the application is crashing.
I tried also the debug mode, but it crashes bevore debuging starts.

Now I tried to check what could be the reason for the crash and therefore I changed the BDA settings in ProgDVB. Default value is FireDTV which I changed to "Microsoft compliant BDA driver". Now ProgDVB is not crashing (I can watch now Astra) but Diseq does not work anymore.

Is there anything what I can do to get the latest ProgDVB version running with FireDTV and Diseq?

Hm. What last good version? I am test FireDTV ~3 month ago.

The last stable version was ProgDVB 6.46.06

But last last version without this problem?

Yes, with ProgDVB 6.46.06 I dont had any issues. No changes to hardware where done on my side. I tried today the new 6.49.7 but same problem again. When I use after installation of ProgDVB for Device option FireDTV, the application is crashing. When I use Microsoft BDA settings, ProgDVB works but without Diseq.

Note: I was using also a DVB-T USB device successfully. I have deactivated it now to get focus only on the FireDTV.

Here are the FireDTV report. Maybe this will help also:
