DVB t/c hybrid tuner like to be c version by default.

I have a new tuner, which is hybrid C/T. But by default, it like to be cable tuner. Unfortunately here is no cable. And Npvr try handle it like cable tuner.
It uses something like USB2875 chip, and emBDA.sys driver from eMPIA Technology. Its own software can use it also T-tuner.
I tried to change its type to dvb-t in Npvr.db3, but it is not enough. Something other trick will needed.

Original software (tvjukebox.exe) started with -dvbc or -dvbt switch from bat. Sub can perhaps figure out, what is difference when calling driver (or something like that). Its over my skills.
Tvjukebox.exe is available here: http://koti.mbnet.fi/jkirjo/TvJukebox/

Has anyone any ideas, how this can be forced to terrestrial reception?
Pinnacle and some others also use this em28xx chipset, which uses this emBDA.sys driver. How they handle this?
