This will work, but isn't a good solution. The card is
only capable of
using one tuner at a time. So if you have an ATSC and
NTSC recording at the
same time, one or both will fail. That's why I
submitted the patch to make
the analog options work for the Kworld card (someone
else did the hard work
for the HD-5500, mine was a one liner). It allows you
to setup the NTSC
tuner as a "daughter card" so only one tuner will be
in use at a time.

On my system I use QAM and have a single cable going
to the top input. I
get both QAM and NTSC from that one cable. I tested
and was able to a tune
a few ATSC stations with the bottom input.

On a side note when I upgraded my kernel a few months
ago the ATSC and QAM
inputs flip flopped on me. Originally ATSC was on top
and QAM was on the
bottom. I don't recall what the upgrade was from or
to, but I'm currently
running 2.6.19.1 with the setup I mentioned above.

I'm starting to think my problem is how this card is
detected. I took the card out and re-installed but it
kept getting detected as a 10Moon PCI TV Card. After
some searching, I noticed a line in my modprobe.conf
that said options saa7134 card=21. Why it did this I
don't know as I didn't add this. Anyhow, I commented
the line out and it picked it up as card=90. The only
problem is that the dmesg says it's tuner=61 and I
would think tuner=68 makes more sense. I then added
the options saa7134 card=90 tuner=68 and then the card
doesn't show up in dmesg. So if tuner=68 is correct,
how do I set this?

Here's my dmesg:

Also, I'm loading the saa7134 module but dmesg says
saa7133.
