I seem to be able to scan some transponders, but not all, using current
code from the repos at http://linuxtv.org/hg/v4l-dvb/ and
http://mercurial.intuxication.org/hg/scan-s2 

I run scan-s2 on the following list of HD-transponders on 0.8w :

S 11938000 H 25000000 3/4 35 8PSK
S 12015000 H 30000000 3/4 35 8PSK
S 12130000 H 30000000 3/4 35 8PSK
S 12188000 V 25000000 3/4 35 8PSK

(a selection of transponders from
http://lyngsat.com/packages/canaldigital.html)

With rolloff set to AUTO scan-s2 will not lock to any transponder.
Instead it will appear to repeatedly re-scan sources on any transponder
the tuner previously was tuned to.

With rolloff set to 35 as above scan-s2 will lock and find channels on
both transponders with SR=25000000, but for the 2 in the middle with
SR=30000000 it simply repeats the channel-list of the previous
transponder. I've been playing with alternatives for rolloff and
modulation with no result.
