[linux-dvb] Technotrend S2-3200 Scanning

Hi Igor,

I've tried using a version from the repository, dvb-utils 1.1.1-3

I also tried to compile the originals from the source tree, unpatched, 
http://linuxtv.org/hg/dvb-apps

I tried to patch "scan" with this scan source: 
http://jusst.de/manu/scan.tar.bz2

And I tried to patch szap with this file:  
http://abraham.manu.googlepages.com/szap.c

But those patched versions won't compile, except for ONE time:

I finally got to compile the patched "scan" (but trying to recompile 
afterwards failed again, very strange) but it *still* didn't scan:

$ sudo scan -t 1 -s 1 dvb-s/Astra-19.2E > ~/channels.conf
scanning dvb-s/Astra-19.2E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12551500 V 22000000 22000000
ioctl DVBFE_GET_INFO failed: Operation not supported
ERROR: initial tuning failed
dumping lists (0 services)
Done.
