Thank you for your input.

No. I stopped the startup services that might cause conflict:
Server4PC (It comes with Technisat Skystar software)
ProgLauncher Application (Installed when you install the ProgDVB)

Bearing in mind that i didn't face this issue with my old SkyStar PCI in the last 8 years ...

Hi ProgDVB team,

I bought recently my new card (TechniSat: SkyStar 2 eXpress HD [4110/3734]), and I installed the drivers and the card worked fine.

However, it's not always stable, sometimes, when i turn on my computer and open the ProgDVB, it still shows signal, however, the channel doesn't open ...
