Got some results:

/dvbscan --dvb-modulation=64-QAM -S 6900 -s 521M:531M

DVB-C: 530.000 MHz, symbol rate 6900 ksym/s, modulation 64-QAMFF6 unc: FFFF
  Str[***********         ] SNR[*****************   ] BER: 9FFFF6 unc: FFFF

Found transport stream at 530.000 MHz.
Scanning for info... [NIT] [PAT 0067] [SDT 0067] [SDT 0067] [SDT 0067]

This is FS Info:

snipplet from ~/.dbv/channels.conf

        service {
                id = 0x0017;
                pmt_pid = 0x0022;
                type = 1;
                name = "SF Info";
                provider_name = "IM-sfi";
        }

This format is not usable for vdr etc. does anybody got an idea how I can 
"translate" that for vdr-usage?

if I do ./dvbrecord --zap --whats-on "SF Info"

Unable to tune to service 'SF Info'**********       ] BER: 9FFFF6 unc: FFFF

hmmm.....

Any ideas?


For "SF Info" I got more infos from the Windooze stuff:
SID: 23
TID:103
NIT: 1
PMT: 34
Video: 336
Audio: 337
PCR: 336
AC3 Audio: 0
Teletext: 339

Whatever that means......
