I agree with you. The latest versions on 6.x series have many bugs and it's always show signal but no quality signal and scanning is done in few seconds with none.

I hope ProgDVB Devs take care of this issue very soon

Tested in:
Windows 7 Build 7000

If you have signal without quality then one of parameters not correct. It is not depended from ProgDVB

Which parameters you mean? The setup configurations?

I can scan and watch channel normally in the card software (Digital TV)

My card is: AD-SP200 - TwinHan 1027

For example quality=0 if you set not correct symbol rate.
In any case this situation depended only from driver and parameters.

Here is how I came over this problem just now:

I copied all.list in:
C:\Program Files\ProgDVB\Transponders
from old version of ProgDVB and replace it with the newer one. The first time I tried to scan the computer get BSOD (Blue Screen of Death) and I after I restarted, it's scan normally and I have all my channels back.Weird isn't ?!

Please note other file with the same name is located in:
C:\Program Files\ProgDVB\Transponders\CabFiles
but replacing this wont do anything. both (old and new version of file) are 14 KB

Use notepad / editor, to look into those.
May well be, you'll find some important difference this way...
