Hello Markus and Roger,
I have had some success getting the v4l-dvb-experimental code working in
Australia with Roger's new xc3028.au2.fw firmware. The attached patch
shows the 2 lines which need to be changed. The first change is setting
input_frequency to 0x2217 and the second is changing the frequency
offset for 7MHz to 2250000. There are two other minor changes in the
patch to remove obsolete code. Obviously, there needs to be a way to
enable the Australia-specific settings at runtime before they can be
The reason why I say that I have had "some success" as opposed to "total
success" is that I am getting patchy reception on some channels and I am
unable to even get a signal lock on others. This might be due to:
a) The 2250000 offset causing frequency settings to map to incorrect
register values, or
b) Bad reception. I suspect this is the case as I have bloody awful
reception on my analog TV. I hope to buy a booster box tomorrow to see
if it makes any difference.
Kudos to Roger and Julian for enabling me to get this far.
