System: Win7 Professional
DVBDream 3.3 (and older)
Hello. Sorry for my english. I'm using Pinnacle PCTV 340e SE tunner for DVB-T on Win 7 Professinal 32bit with DVBDream a long years on the same computer, device and antenna.
Last time I watched DVB-T 26.4.2017 and it was OK. Since then, I have not made any installation or upgrades on my PC. April 29, 2017 I saw only a black picture and no sound. When I try to debug channels, DVBDream can not tune in any channel. Always reports that "No channels found!" and "TP is empty". Im trying completly new installation DVBDream (unninstall, deleting all files and folders, ddfix.exe, restart, and new install) - without success.
Other programs all available channels tunning and play (MPC-HC, VLC, P***DVB) OK - on the same PC! I have installed DVBDream 3.3 on the other notebook (win 7 Home 64bit) and everything works fine too. All channels are tuned and playing well. I use the same BDA device and the same edition DVBDream 3.3.
When I transferred chlist.chl from function installation to my PC, DVBDream Channel List shows all channels, signal Level is from 21% to 41%, and 100% quality,

but screen is black, sound is noice and I still can not display (or tune) any channel, when I trying tunnig it again.
During scanning shows DVBDream only:
Scanning 690000 Khz (bw:8)... L:29% Q:29%
Scanning 578000 Khz (bw:8)... L:24% Q:24%
Scanning 722000 Khz (bw:8)... L:30% Q:30%
What can I doing? Help me, please.
