Daryl,

You are correct about the number, 0/1.
However, just to be sure that you are not getting some system default, 
which may change between boots, try using adapter_nr=3 and verify this 
on reboot using dmesg.
The usual range for adapter_nr is 0-7, but depends on how the kernel was 
built. For Ubuntu stock kernels it is 0-7.

I usually leave adapter_nr=0,1 free for testing of additional cards.

If you still get problems please post contents of the dvb-options.conf file
