Hi Damien,

Have you tried to do a full scan by yourself using dvbscan instead of
using the supplied channels.conf from Chris?

Since there was no channels.conf available for me I had to do that for
myself by building a au-Wollongong file from the frequencies given at
dba.org.au for my area.

I don't know if this would help but at least you would be doing things
from scratch to get the channels, I have got SBS with no troubles where
I am.

With Chris's new changes I didn't have to apply any offsets to channel
frequencies at all.

Cheers,

Brett

  Hi Brett,
Jurgen and others,

  After
failing to compile Chris’s test
DVB sources for the DViCO Dual Digital card for about a week on all
sorts of
different kernels, the patches have made their way into the main dvb
sources J  And
they work!!  Schweet!  Thanks
Chris!

  With one
small hitch – I am having
problems with tuning SBS.   I am using 2.6.17.8
vanilla sources, and the v4l-dvb mercurial sources, about 2 days after
Chris’s
patches went into the v4l-dvb tree.

  I am using
the channels.conf file supplied
for Brisbane
on
Chris’s website.

  In the past,
with the 2.6.18-rc3 kernel
out of the box allowed me to tune all channels, albeit Channel 9 and
SBS
required the +166667Hz offset.

  Currently:
  -         
  Channel
9 tunes quite nicely with a +166667Hz offset.
  -         
  ABC,
Seven and Ten all tune nicely without offsets
  -         
  SBS
refuses to tune (SNR reported by tzap is roughly 5xxx for 10-20s,
followed by a
brief lock at approx dxxx for 5seconds , then drops out to 0000 forever)
  -         
  SBS does
this for 0 offset, +166667 offset and -166667 offset.  The
behaviour is quite repeatable.

  And
furthermore, on (I think) the USB part,
tzap –a1 with an offset of +166667, SBS tunes with an
snr of about dddd, and manages to hold it.   
  Even more confusing, using tzap –a0 “SBS HD” (same
+166667 offset channels.conf file) on the other adaptor results in the
behaviour
above.

  On –a1,
Channel 9 tunes (with
offset) nicely as does the others, without an offset.

  Any further
ideas?  Is there any other
information I can provide?

  Cheers
  Damien.

  Yes, Chris
e-mailed me himself and said as
much but after downloading and using I’m still having no results. I
thought maybe at first it could be my current dodgy Arial setup but I
have just
come back from my mates place whom has a digital set top box etc, that
works
great with no success either. L

  http://pastebin.ca/123294
 shows you the results of my scan, as you can tell it’s not very
exciting. L after
completing this I find this

  DVB: demodulator offset
has changed for frontend
"Zarlink ZL10353 DVB-T". Please report tuning difficulties to linux-dvb@xxxxxxxxxxx

DVB: freq: 191625000, div: 1367 -> 1366, offset: 36166667 ->
36166667,
actual: 227665756 -> 227832422

  In my dmesg/messages log.
I’m going to send the
info to chris and see if there is still something wrong or if I’m just
doing something completely stupid. :\

  Hi
Jurgen,

Chris has only just made some modifications to the driver for this card
due to
its new chipset.

Try a build from Chris's lastest hg tree;
  hg clone http://linuxtv.org/hg/~pascoe/v4l-dvb-test/
  following the "how to build
from hg"
instructions.

This driver fixed my DVB-T plus tuning problems and I can tune all my
channels
down here in Wollongong.

Hopefully Chris doesn't mind me passing this info on, once again thanks
to Chris
for the great work!

Regards,

Brett
