I tried the advice of both of the replies that I got below.  I get the
following in dmesg.

Originally a friend helped me by getting setting up the system to look for
the old dvico fusion 5 card.
I put

options cx23885 card=4

in /etc/modprobe.d/options.  The system would recognize that I had a card
with two feeds, but I could get channels on the scan.  I commented out this
line and then tried installing the deb package, but lost support of the
I tried installing from source, but that didn't help.  I tried installing
the firmware as recommended, but it still didn't help.
At some point it recognized only one feed, still couldn't get channels on
the scan.  Then I lost the card completely.  I admit that I just started
trying suggestions and was probably not systematic enough.  I may need to
scrap the install and start over.  Since the box is new, that is not a big
deal.  It probably wouldn't take very long to reinstall.

I have some questions.  Will there be support for both tuners?  The old
driver seemed to support 2, so I would hope the new one would too.  Will
this card not work with analog channels or has support just not been written
yet?  If I do have analog channels, what should the settings be?  Would one
of those digital converter boxes make it a digital signal? (That is probably
a dumb question, but this is not really my area.)

Thanks for all of your help.




The support that I added in was for a the DViCO DVB-T Dual Express, not the

However there may be good news for you...
If your card is the FusionHDTV7 Dual Express there is support for this card
in the main tree (only one DVB tuner at the moment). This may not help you
as you stated that you needed analog support.

The easiest way for you to get the newest DVB drivers is to go to this

You may need to install some firmware as well (you can tell if you need to
get the firmware by an error message in the syslog [accessed by typing
"dmesg" in a terminal], this error will only show up after you try to scan
or tune to a channel.  If you need firmware goto:
and follow the instructions inside the files (extract.sh and readme.txt).

Give that a go then come back, with any issues to the mailing list.

Perhaps you could create a wiki page on: http://linuxtv.org/wiki/index.php
with all the relevant information on it, for an example checkout:
And if you do make the page, update this page while you are at it:
