Looks to me like Danesh has a different problem...  He said he's
getting static from the first tuner (he calls it "video0", you call
it "tuner 1"), while the second works fine.

I have a problem with mine where the first tuner works fine and the
second tuner returns nothing, though, and haven't been able to get
anything definitive from ivtv-users...  Guess I'll have to check out
ivtv-devel and see what I can find there.

Oh, looks like you're affected by the problem under discussion on
ivtv-devel?  Do you show a bunch of errors in dmesg that look like
"ivtv warning: i2c client addr: 0x44 not found for command
0x40046406!"?  If so, that's the same problem I have...  (Danesh,
OTOH, is definitely having a different problem than I am, since he
initializes without any of those errors.)

This is what I would look at first.  Are you sure you have the right
firmware binaries in /lib/modules?  Here's what I've got in mine:

-r--r--r--  1 root root  14264 2005-08-27 20:14 HcwMakoA.ROM
-rw-r--r--  1 root root 262144 2005-08-27 20:12 ivtv-fw-dec.bin
-rw-r--r--  1 root root 262144 2005-08-27 20:12 ivtv-fw-enc.bin

# md5sum HcwMakoA.ROM ivtv-fw-dec.bin ivtv-fw-enc.bin
3a4803384f749d644ee1f1ca9dcb12fa  HcwMakoA.ROM
305dba74bbe5905447add8883f3ecb68  ivtv-fw-dec.bin
ab75947ef1b086e26f9b08e628baa02e  ivtv-fw-enc.bin

If yours don't match, you may want to try downloading an older
ivtv-fw-enc.bin/ivtv-fw-dec.bin and see if that helps.  (A check of
my dmesg output shows that I'm using revision 0x02040011, as
recommended by the warning you're getting.)
