Hi, i'm having problems with my new DVB-C device on UPC DVB-C network (Bratislava, Slovakia, encrypted using Conax CAM module inserted in CI slot connected to the DVB-C card):

The result of scan for channels using GlobeTV (the Windows app) was this : http://pastebin.com/XNHvjAfb . Because i'm using a cable operator not listed in /usr/share/dvb files, i need to use w_scan and the result is something like this : http://pastebin.com/0fUS6Tzx . Because of those filter timeouts, it finds no channels using the same cable and card which had no problems on Windows and using the same cable which has no problems with the provided set top box from the cable operator. You might suggest me to use dvbsnoop, but only two commands which work are the signal and feinfo. pidscan returns nothing : # dvbsnoop -s signal dvbsnoop V1.4.50 -- http://dvbsnoop.sourceforge.net/ --------------------------------------------------------- Transponder/Frequency signal strength statistics... --------------------------------------------------------- cycle: 1 d_time: 0.001 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 2 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 3 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 4 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 5 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 6 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 7 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 8 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 9 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 10 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 11 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 12 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 13 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 14 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 15 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 16 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 17 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 18 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 19 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 20 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 21 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 22 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 23 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 24 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 25 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 26 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 27 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 28 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 29 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 30 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 31 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 32 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 33 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 34 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 35 d_time: 0.008 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] cycle: 36 d_time: 0.007 s Sig: 65535 SNR: 65535 BER: 1019791 UBLK: -1886417009 Stat: 0x1f [SIG CARR VIT SYNC LOCK ] ... #

Signal level according to the set top box is ~57%, signal quality is 97-99%, and as i mentoined, set top box works without problems, and it works using this DVB-C card and same cable when using with Windows (but true, on different PC). Any ideas ?
