-D num, --device=num
Use only the given DVB device (num = 0, 1, 2...).
There may be several -D
options (by default all DVB devices will be used).
The way I first read that, to make it use device 1 and 2 and not 3, you
would use:
-D 1, 2
or:
-D 1,2
But it seems you can't put more then one per "-D". You have to use:
-D 1 -D 2
