I installed the updated version of ProgDVB Pro, 64 bit V7.1, Engine Version 6.125. On the early version all worked OK, but with the new version every time I shut ProgDVB and then restart, my channels are still listed in the left hand column, but no channel will play. Both "L" and "Q" are very low. When I do a channel search all the channels are found again and then they work. Close down and run the prog again and I can't watch a channel till I do the channel search again.

Channel search works OK, but it is not remember on restarting.
Haswell CPU 26G RAM, GTX 660 Video card. DVB-T signal.

Check TV sources.

ps: What last good version?

Sources are fine. Sources show the two tuners in my dual USB tuner.
Previous version was 7.08.1.0
Forgot to say I have Win 8.1 64 with the previous version of ProgDVB and the current 7.1

2 dvb-t tuners? Check Multi channels options in ProgDVB.

ps: No important changes in ProgDVB for you case very long time. may be some problem with import of old list or TV Sources.

Yep dual tuner. This is it http://avertv.avermedia.com/avertv/Uplo ... 130102.pdf .

TV sources look fine to me. see attachment

It is very untypical device because only one tuner for 2 modes. Best if you need one mode for example DVB-T.
