Hi, side note : the problems in my previous post "KNC1 TV-Station S, revision 0x1894, doesn't tune", were related to the PCI-slots of the motherboard I used rebuilt the machine around a new motherboard, both KNC1's are now recognized and able to tune lesson learnt : check the hardware before complaining about the software ... next step is accessing the scrambled signals as I said, the cards scan OK and using "szap" I can tune to them : mythtv@silverstar:~> szap -a 1 -c channels.conf VT4 reading channels from file 'channels.conf' zapping to 795 'VT4': sat 0, frequency = 12669 MHz V, symbolrate 22000000, vpid = 0x03af, apid = 0x039b sid = 0x31e5 using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0' status 05 | signal 9ffb | snr 21f6 | ber 0000ea08 | unc 00000000 | status 1f | signal d430 | snr dad3 | ber 00000100 | unc 00000000 | FE_HAS_LOCK status 1f | signal d47e | snr dab5 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d5b8 | snr dacd | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d458 | snr dac7 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d5bc | snr daf7 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d460 | snr da9a | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d47c | snr daac | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d46c | snr dac1 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d465 | snr dabe | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d481 | snr dabb | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d46f | snr dab5 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d43b | snr daa0 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d468 | snr dabe | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d47e | snr daa6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d342 | snr dac1 | ber 00000000 | unc 00000000 | FE_HAS_LOCK mythtv@silverstar:~> szap -a 1 -c channels.conf VTM reading channels from file 'channels.conf' zapping to 793 'VTM': sat 0, frequency = 12669 MHz V, symbolrate 22000000, vpid = 0x03ad, apid = 0x0399 sid = 0x31e3 using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0' status 1f | signal d404 | snr b772 | ber 0000c000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d479 | snr da8b | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d5b7 | snr daac | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d5b6 | snr da97 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d47c | snr daa0 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d5bb | snr da70 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d342 | snr da97 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d480 | snr daa6 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d340 | snr da97 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d481 | snr da40 | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d47e | snr da6a | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d340 | snr da6d | ber 00000000 | unc 00000000 | FE_HAS_LOCK status 1f | signal d468 | snr da91 | ber 00000000 | unc 00000000 | FE_HAS_LOCK both VTM and VT4 are encrypted channels here, so no mpg-output at this time I have found one (1) encrypted channel that works using gnutv : mythtv@silverstar:~> gnutv -adapter 1 -channels channels.conf -out dvr VTM Using frontend "ST STV0299 DVB-S", type DVB-S status SCVYL | signal d47c | snr dac1 | ber 0000ff00 | unc 00000000 | FE_HAS_LOCK CAM Application type: 01 CAM Application manufacturer: 0100 CAM Manufacturer code: 0000 CAM Menu string: CANALDIGITAAL CAM supports the following ca system ids: 0x0100 Received new PMT - sending to CAM... mythtv@silverstar:~> using mplayer, I have a clear picture this proves to me that descrambling works but I have yet to find another channel that works, even on the same transponder frequency none of the others work !? what's more, it looks like it's the CAM that's the cause of things : first, remove the CAM from the CI slot : mythtv@silverstar:~> gnutv -adapter 1 -channels channels.conf -out dvr VT4 Using frontend "ST STV0299 DVB-S", type DVB-S status SCVYL | signal d464 | snr da9a | ber 0000a700 | unc 00000000 | FE_HAS_LOCK the lock is immediate insert the CAM, same command : mythtv@silverstar:~> gnutv -adapter 1 -channels channels.conf -out dvr VT4 Using frontend "ST STV0299 DVB-S", type DVB-S CAM Application type: 0140 | snr 83c1 | ber 0000ff00 | unc 00000000 | CAM Application manufacturer: 0100 CAM Manufacturer code: 0000 CAM Menu string: CANALDIGITAAL CAM supports the following ca system ids:er 0000ff00 | unc 00000000 | 0x0100 mythtv@silverstar:~> c82e | snr a15e | ber 0000ff40 | unc 00000000 | so gnutv accesses the CAM, and the signal and SNR drop to unusable levels ? the same happens for unencrypted channels : the signal and SNR drop if a CAM is present and gnutv is used NO CAM : mythtv@silverstar:~> gnutv -adapter 1 -channels channels.conf "BBC World" Cannot open decoder; defaulting to dvr output Using frontend "ST STV0299 DVB-S", type DVB-S status SCVYL | signal ccf4 | snr d6b6 | ber 0000ff00 | unc 00000000 | FE_HAS_LOCK INSERT CAM : mythtv@silverstar:~> gnutv -adapter 1 -channels channels.conf "BBC World" Cannot open decoder; defaulting to dvr output Using frontend "ST STV0299 DVB-S", type DVB-S CAM Application type: 0156 | snr 81ed | ber 0000ff00 | unc 00000000 | CAM Application manufacturer: 0100 CAM Manufacturer code: 0000 CAM Menu string: CANALDIGITAAL CAM supports the following ca system ids:er 0000ff38 | unc 00000000 | 0x0100 mythtv@silverstar:~> bcc0 | snr a05f | ber 0000ff18 | unc 00000000 | szap is not bothered by the presence of a CAM (because it doesn't access it ?), tuning works fine with and without one questions : why does inserting and accessing a CAM reduce the signal and SNR levels ? (even if no descrambling is needed, as for BBC World) how can this be solved ? anyone out there having the same problems ? thanks, Luc _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
