DVICO Fusion Dual Express DVB-T - Australian Channel Problems

["Daniel" <zhennian@fastmail.fm>]

I've been working to get my DVICO Fusion Express DVB-T (rev 02)
PCIe tv capture card working for a few months now.

I've had some success with the
[1]http://linuxtv.org/hg/~stoth/v4l-dvb-cx23885 repository on
linuxtv.org, managing to get the remote to work and most channels
to tune reasonably reliably. Thanks to Steve for the great work
on this.

Im using the xc3028-v27.fw firmware file and kernel version
2.6.28-13-generic under jaunty.

lspci entry is:-
04:00.0 Multimedia video controller [0400]: Conexant Systems,
Inc. CX23885 PCI Video and Audio Decoder [14f1:8852] (rev 02)

After some troubleshooting, it seems that channels tune fine
after a reload of the module, but otherwise the card will not
re-tune to another channel. You can tune once on each of the
receivers before they lock out and the module needs to be
reloaded.

I know my reception is fine because the WinFast DTV1000 in the
same machine is rock solid on all channels.

I noticed on some lists that someone has claimed success with the
main v4l-dvb repositorty, but this does not tune at all for me.
