TBS 6522 dual tuner DVB-T/T2/S/S2 does not find SD DVB-T channels

Hi,
I recently updated to new PCIe card TBS 6522, which supports DVB-T/T2/S/S2.
DVB-S/S2 and DVB-T2 channels work perfectly with newest ProgDVB x64, but DVB-T frequencies fail to lock even when there's 70% signal strength, with manual or auto search. T2 channels are found normally from both 7 and 8 MHz bandwidth.
I'm using latest TBS BDA drivers 1.0.1.2, which show two tuners in ProgDVB, one for T/T2 and one for S/S2. Card is much more sensitive than my old Terratec 1200S + Astrometa T2 USB.
Peculiar thing is that SichoPVR finds DVB-T channels normally. My old Astrometa T2 presented two tuners, one for T and other for T2.
I contacted TBS but they could not figure it out. I don't want to use SichoPVR, so I'd highly appreciate a fix/workaround in ProgDVB.
Best regards,
Pasi

Tried changing Additional API of Tuner 1 (DVB-T/T2) into Astrometa, but after that it is incorrectly identified as DVB-C and does not work. Automatic puts it as 'TBS, Prof'
In the latest ProgDVB Professional 7.21.05 I'm also experiencing strange behavior when changing from channel to another: It seems that the codec is not updated, so changing from DVB-S2 into DVB-S channel keeps (according to the OSD) the previous audio/video codecs and displays a blank screen. However, pressing green stop button and moving to new channel works ok.

Yes, one tuner for DVB-S/S2 and one for DVB-T/T2.
In other words, terrestial tuner is shown as one.

Tried 'Symbol rate in kilo-symbols' off and on, no difference. DVB-T-only transmitters, such as strong (signal level 60-70%) Digita 562MHz/8MHz still fail to lock or find any channels with manual search, while DVB-T2 (such as DNA 177.5MHz/7MHz) transmitters work well. SichboPVR finds both DVB-T and T2.

This debug build, self-signed - so need enable testmode for Win x64 or temporary disable signature cheking.

Hi, and thank you -
Installed 1.0.0.3 debug driver, and now DVB-T channels are found normally with manual and automatic scan. It also seems that channel switching is faster!
When might these fixes become part of signed drivers?
EDIT: I'm naturally talking about 1.0.1.3 debug driver.

TBS released an official 1.0.1.3 version yesterday, but it seems to break DVB-T/T2 support altogether from TBS6522. Reverted back to CrazyCat version.

Hi CrazyCat, would you know if the official 1.0.1.3 driver will be updated to support this card properly? I still have to run your driver in test mode
