Solved, in vtuner_main.c, line 43
#define VTUNERC_MAX_ADAPTERS    4
replaced with
#define VTUNERC_MAX_ADAPTERS    32

Just added compiled-time option for that. You can easily change number of 
supported DVB devices by the following make command:
make VTUNERC_MAX_ADAPTERS=8

Checkout fresh source and test yourself.
