Hi list,
I've been struggling with this for awhile now and I'm in need of some insight. The problem seems to be that the front end is unable to tune to or monitor a signal. Here is some background info:

Card:
Twinhan 1025 VisionPlus PCI DVB-S
Kernel/Dist:
2.6.17.8, Debian testing.
I just used hg to download the latest v4l-dvb and dvb-apps from Mercurial and everything compiled and installed fine. The drivers all modprobe fine. I modpobe in this order:
dvb-core
bttv
dvb-bt8xx
dst

Is there anything I'm missing there?
dmesg says:
###############dmesg#####################
DVB: registering new adapter (bttv0).
dst(0) dst_get_device_id: Recognise [DST-03T]
dst(0) dst_get_device_id: Unsupported

###########################################
this seems fne to me.
Now the problems...
dvbtune to the satellite Galaxy 10R at 123 degrees west., I'm in southern California:

# dvbtune -f 11800000 -p V -s 26657
Using DVB card "DST DVB-S"
tuning DVB-S to L-Band:0, Pol:V Srate=26657000, 22kHz=off
polling....
Getting frontend event
FE_STATUS:
polling....

polling....

Just goes on and on polling...

Then I look a dvbsnoop frontend info:

# dvbsnoop -s feinfo
dvbsnoop V1.4.00 -- http://dvbsnoop.sourceforge.net/

---------------------------------------------------------
FrontEnd Info...
---------------------------------------------------------

Device: /dev/dvb/adapter0/frontend0

Basic capabilities:
   Name: "DST DVB-S"
   Frontend-type:       QPSK (DVB-S)
   Frequency (min):     950.000 MHz
   Frequency (max):     2150.000 MHz
   Frequency stepsiz:   1.000 MHz
   Frequency tolerance: 29500
   Symbol rate (min):     1.000000 MSym/s
   Symbol rate (max):     45.000000 MSym/s
   Symbol rate tolerance: 0 ppm
   Notifier delay: 0 ms
   Frontend capabilities:
       auto inversion
       FEC AUTO
       QPSK

Current parameters:
   Frequency:  0.000 MHz
   Inversion:  AUTO
   Symbol rate:  26.657000 MSym/s
   FEC:  FEC AUTO

You can see that the freq is not set. An interesting note is that up in the basic capabilities section is lists frequency(max) as 2150.00 MHz. Is that right? The Ku-band satelite frequency is listed on lyngsat.com as being 11800 MHz. What am I missing there?

Heres an interestng error from dvbsnoop:

# dvbsnoop -pd 9 -s signal
dvbsnoop V1.4.00 -- http://dvbsnoop.sourceforge.net/
  DEMUX : /dev/dvb/adapter0/demux0
  DVR   : /dev/dvb/adapter0/dvr0
  FRONTEND: /dev/dvb/adapter0/frontend0

---------------------------------------------------------
Transponder/Frequency signal strength statistics...
Capabilities: BER: 1  SNR: 1  SIG: 1  STAT: 1  UBLK: 1
---------------------------------------------------------
Error(95): frontend ioctl: Operation not supported
cycle: 1  d_time: 0.001 s

I've searched but I can't figure out what the Error(95) is .  Any ideas?

a similar message comes from dvbtune:
# dvbtune -m
FE READ_BER: : Operation not supported
FE READ UNCORRECTED BLOCKS: : Operation not supported
Signal=0, Verror=0, SNR=0dB, BlockErrors=0, ()
FE READ_BER: : Operation not supported
FE READ UNCORRECTED BLOCKS: : Operation not supported
Signal=0, Verror=0, SNR=0dB, BlockErrors=0, ()
FE READ_BER: : Operation not supported
FE READ UNCORRECTED BLOCKS: : Operation not supported
Signal=0, Verror=0, SNR=0dB, BlockErrors=0, ()
FE READ_BER: : Operation not supported

and on and on..

Finally I get this from every option of dst_test that I run. I can't find any documentation on this app though, so I'm not sure how it's supposed to work.
# dst_test -i
main: Error opening /dev/dvb/adapter0/ca0

This seems to be because ca0 is missing:
/dev/dvb/adapter0# ls
demux0  dvr0  frontend0  net0

I would REALLY apprecate any help or insght you might have on this. thank you very much for your consideration.

Dave
