[vdr] Pb with Viacess2 CAM on budget card with vdr 1.3.17

[Dominique Dumont <domi.dumont@free.fr>]

Hello

I have a single budget card (Twinhan clone: Hercules Smart TV satellite) with 
a Viacess2 card (the red one) and a TPS W card.

According to dmesg, the CAM is found by DVB drivers:

   bttv0: using: Twinhan DST + clones [card=113,insmod option]
   bttv0: gpio: en=00000000, out=00000000 in=00f500fd [init]
   bttv0: using tuner=4
   tuner: Ignoring new-style parameters in presence of obsolete ones
   bttv0: add subdevice "dvb0"
   bt878: AUDIO driver version 0.0.0 loaded
   bt878: Bt878 AUDIO function found (0).
   bt878(0): Bt878 (rev 17) at 01:07.1, irq: 19, latency: 32, memory: 0xd8001000
   attach: checking "bt878 #0 [hw]"
   find by pci: checking "bt878 #0 [hw]"
   attach: "bt878 #0 [hw]", to card 0
   DVB: registering new adapter (DST).
   bt878 find by dvb adap: checking "DST"
   dst_check_ci: recognize DST-CI
   DST type : satellite
   DST type flags : 0x1 newtuner 0x2 ts204
   DVB: registering frontend 0:0 (DST SAT)...

Unfortunately, vdr 1.3.17 does not detect the CAM. The Setup-CICAM reports:

   CICAM DVB1 1   -
   CICAM DVB1 2   -
   CICAM DVB5 1   -
   CICAM DVB5 2   -

BTW, Why does it report 2 DVB cards ?

When switching to an encrypted channel, user log shows:

  Dec  4 11:07:33 localhost vdr[4311]: switching to channel 6
  Dec  4 11:07:34 localhost vdr[4318]: transfer thread started (pid=4318, tid=81926)

  Dec  4 11:12:37 localhost vdr[4315]: channel 6 (TF1) event 11:12 'STAR ACADEMY' status 4

I've re-compiled ci.c with:

  static bool DumpTPDUDataTransfer = true;
  static bool DebugProtocol = true;

but nothing CAM related shows on the STDOUT of vdr:

  $  LD_ASSUME_KERNEL=2.4.1 ./vdr -P softdevice
  [softdevice] processing args
  [softdevice]   argv [0] = softdevice
  [softdevice] initializing Plugin
  [softdevice] Initializing Video Out
  [softdevice] ffmpeg version(0.4.8) build(4680)
  [softdevice] Xv out OK !
  [softdevice] Video Out seems to be OK
  [softdevice] Initializing Audio Out
  [softdevice] Audio out seems to be OK
  [softdevice] A/V devices initialized, now initializing MPEG2 Decoder
  cSoftDevice::MakePrimaryDevice
  [softdevice] should set volume to 255


Other weirdness that may be related, Setup-DVB menu reports that my
"Primary DVB interface" is 2. Although I have only one DVB card. (The
only other video inpout card in my Radeon 9200 VIVO which is not
configured for video input). Free to air channels like Euronews works
correctly on DVB 2. If I force the "Primary DVB interface" to 1,
Euronews does not get through.


So any hint on how to fix this problem ?

Thanks
