[linux-dvb] [PATCH] DIB3000MC and NOVA T USB2

       Well, the channels in my channels channels.conf have a defined
FEC_ (no auto), the only _AUTO (and, in all of them) is

       Thanks anyway. I'm just trying to figure out why that strange
behaviour in some channels and the "magic" of tunning to the 0 ber/unc

       I'll wait the "antenna guy", who must review my antenna
installation someday next week anyway :)
