Oh well, as insmod parameter it is ok. To make it clear:
using "make insmod"  ---> pids_off=0
using insmode by hand (no parameter pids_off) pids_off=1

That means if I do insmod in this way:
  insmod dvb.o init_chan=2 readfirm=1;
the tuning problems Klaus described (and I observed too) should not
happen? Btw. what is the purpose of readfirm=1?

(grep through the DVB src:
driver/Makefile:        insmod dvb.o init_chan=2 pids_off=0 readfirm=1; \
driver/dvb.c:static int pids_off=1;
)
