Quotation marks may be needed…try appending via command line as well.

What is DAQ?  I have seen that, but have no idea what that is.
As far as my bpf file goes, if it is like this::
 
#not net 10.10.0.0/24 and not net 10.30.0.0/24
not net 10.10.0.0/24 and dst host 10.75.45.1 && dst port 80 or not net 10.30.0.0/24 and dst host 10.75.45.1 && dst 
port 80

It will fail with::
Reading filter from bpf file: D:\Snort\etc\ignore2.bpf
ERROR: short read D:\Snort\etc\ignore2.bpf (169 != 170)
Fatal Error, Quitting..
 
If I remove the commented line, then snort starts fine.
If I try to have multiple lines in the file, (all being rules, no comments) the it will fail with a similar error as 
above.
I have never seen a DAQ error.

Snort does allow comments in the BPF file, starting with # to end of line.  If there is a syntax error, you should 
see something like:
 
ERROR: Can't set DAQ BPF filter to '
...      
' (pcap_daq_set_filter: pcap_compile: syntax error)!
Fatal Error, Quitting..
 
What DAQ are you using?  Please send the BPF file that fails and the error that you get.

But any ideas why snort fails to start if I add in a '#' to comment a
line??

i have no clue but it sounds like a coding error not allowing comment lines i
the BPF file... only joel or one of the snort dev guys can tell us that... or
possibly a code diver who can root around in the snort code ;)
