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 :-)  And they work!!  Schweet!
Thanks Chris!
With one small hitch – I am having problems with tuning SBS.   I am using 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.
-          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
Any further ideas?  Is there any other information I can provide?

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. :-(
http://pastebin.ca/123294  shows you the results of my scan, as you can tell
it’s not very exciting. :-( after completing this I find this
DVB: demodulator offset has changed for frontend "Zarlink ZL10353 DVB-T".
Please report tuning difficulties to linux-dvb at linuxtv.org
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!
