I can't get the scan/scan-s2 utilities to lock any transponders

This is probably some simple user error on my part, but I can't figure
it out. I have a Corotor II with polarity changed via serial command
to an external IRD. C/Ku is switched by 22KHz tone, voltage is always
18V. Ku is with tone off, C with tone on. Speaking of which, is
there a way to manually set the tone from the arguments on the scan
utilities?
Here's what I've tried and the results:
$ ./scan-s2 -a 0 -v -o zap -l 10750 INIT
API major 5, minor 0
scanning INIT
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Same thing happens if I use just 'scan' and not 'scan-s2.'
If I use dvbtune, it works though..
$ dvbtune -f 1350000 -p H -s 20000 -c 0 -tone 0 -m

I'm using v4l-dvb drivers from the main repo as of about a week ago.
I am running kernel 2.6.32 on Debian testing. Any help is appreciated
..and hopefully it's just a simple flub on my part!

Try using a non-auto FEC and rolloff.
Some devices won't accept auto for these parameters.
Cheers,
Lou
