[linux-dvb] skystar2 problems

[Michal Svec <rebel@atrey.karlin.mff.cuni.cz>]

Hi!

I have problems with a skystar2 card (tested with the latest
1.0.1 driver):

  bash# ./apps/szap/szap -c ~/Astra1 -n 73
  reading channels from file '/home/rebel/Astra1'
  zapping to 'CNN Int.':
  sat 0, frequency = 11778 MHz V, symbolrate 27500000, vpid = 0x00a5, apid = 0x0064
  using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
  status 00 | signal 0000 | snr 73f5 | ber 00000000 | unc 00000000 |
  status 1b | signal 3dc5 | snr c7d1 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
  status 1b | signal 3dc1 | snr c7e9 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
  status 1b | signal 3dbf | snr c7bd | ber 00000000 | unc 00000000 | FE_HAS_LOCK
  status 1b | signal 3dba | snr c7e9 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
  status 1b | signal 3dbc | snr c7f5 | ber 00000000 | unc 00000000 | FE_HAS_LOCK
  ...

The status 1b is suspicious, so I'm not very surprised that I don't get any
output, for example with 'dvbstream -o -f 12441 -p v -s 27500 512 660':

The new driver with added support for the revision 2.6 is even worse
(got it from http://www.gdv.uni-hannover.de/~peinecke/skystar2):

  bash# ./apps/szap/szap -c ~/Astra1 -n 73
  reading channels from file '/home/rebel/Astra1'
  zapping to 'CNN Int.':
  sat 0, frequency = 11778 MHz V, symbolrate 27500000, vpid = 0x00a5, apid = 0x0064

  status 00 | signal 3df2 | snr 8329 | ber 00000000 | unc 00000000 |
  ...

So, any hints what I could try next?

Thanks
Michal
