Hello all,
I tried to upgrade kernel to 2.6.20 just to notice that one multiplex on
our local "Welho" cable (138 Mhz, QAM128, 6.9msym/s). With 2.6.18.1 it
works just fine:
mythtv:/home/mythtv# czap -a 1 -c ~mythtv/.czap/channels.conf "Discovery"
using '/dev/dvb/adapter1/frontend0' and '/dev/dvb/adapter1/demux0'
reading channels from file '/home/mythtv/.czap/channels.conf'
31 Discovery:138000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_128:900:901:406
31 Discovery: f 138000000, s 6900000, i 2, fec 0, qam 4, v 0x384, a 0x385
status 1f | signal 0325 | snr 10be | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 0326 | snr 10cf | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
status 1f | signal 0326 | snr 1129 | ber 00000000 | unc 00000000 |
FE_HAS_LOCK
....
but there is no lock if I boot with 2.6.20 kernel. Other multiplexes
with similar parameters (QAM, symbol rate), work just fine. I am using
technotrend dvb-c 1500 card equipped with CI & Conax CAM module.
Could you give an idea what would be needed to debug this? I can provide
debugs and other data, but don't know what you developers need in order
to isolate the problem.
