You have to use /dev/dvb/adapterX/ where X is the number of the DVB 
Adapter you want to check.

Can you please try to narrow down this problem?

They are kernel threads, part of the driver to keep the hardware running 
and reset the ARM firmware/frontends when necessairy. They will be 
stopped when the driver gets unloaded.

arm_mon is a bit misleading, maybe we should rename this thread - it 
should better start with kdvb...
