Here's a diff for the changes I made to the cx88-atsc.c source file in
the 2.0 driver.

First, thanx for the responce Greg.
Actually, I have Over the Air Digital ATSC (in the States, pulling
from a
Digital Antenna). And the tuner card is actually working as I am able
to pull
up a picture using mplayer /dev/video2 . The tuner card/driver
(which
is the
cx88-atsc driver) seems to be working fine. The issue 'appears' to
be
something myth related in this kernel/driver configuration.
Otherwise
I don't
know why I can view TV from mplayer accessing this tuner card ( I
just have
to change channels by issuing a 'dtvsignal /dev/video2 <channel
number>'
command). Myth seems to see the card, but can't find the inputs
(i.e.
Television, Composite, S-Video). Kinda strange.
By the way, the same box, booting a 2.6.8 kernel, works fine with
myth, but I
have to use the HD-3000 1.5 drivers to compile on this kernel.
I believe I had this same problem with the 2.0 cx88-atsc driver for
the
HD-3000. I ended up actually modifying the driver itself slightly,
because it didn't appear to be responding to the call Myth makes to
query the inputs. All works fine now, but I have hoped to find a way
to get it to work without a custom modification to the driver. If you
figure it out please post your findings. Otherwise I'd be glad to
provide the changes I made to the driver if you want to try it.
