I use a Hauppauge Nova-se2 Tv-card in my pc and I seem to get only channels below a frequency of 12050 Mhz in H and V polarisation. I use Astra 19.2° East and a digital single LNB from Technisat.
I tried find some answer with google and it seems my tv-card doesn't switch to highband?
Is this correct? I read somewhere that Hauppauge cards might have a problem with the 22khz signal to switch to the Highband but I found no proper solution so far.
Did somebody had a similar problem? What can I do to check this?

Do you have any diseq devices?

no, just a single lnb, directly connected to the tv-card.

I am not have good idea about ProgDVB side. But check LNB type and switch value.

ps: Is it BDA?

In ProgDVB it is shown as DBA. I installed the standard Hauppauge driver.
Is there something like a test-software, so I might check if the 22khz signal is working?
I will try another tv-card soon.

I have ProgFinder, but recommend use other software for test.

ps: You problem looks like hardware or in driver...
