Hi Brett, Jurgen and others,
After failing to compile Chriss 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!
With one small hitch I am having problems with tuning SBS. I am using
22.214.171.124 vanilla sources, and the v4l-dvb mercurial sources, about 2 days
after Chriss patches went into the v4l-dvb tree.
I am using the channels.conf file supplied for Brisbane on Chriss 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 Im 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
its 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. Im going to send the info to chris and see if
there is still something wrong or if Im just doing something completely

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!
