It's worth noting that MythTV has tried to use the card.  It's default 
resolution for the bttv card is 480x480, so I'm not sure what's 
happening here.  On other attempts I've seen it start up at 720x480.

I have not tried that.  This is an nForce4 board, with PCIe, so I 
believe that pretty much guarantees that it's PCI 2.3.  In addition I 
verified that I have a subtractive pci bridge, if I remember your 
earlier posts.  I did as you suggested there, and read the whole i2c/pci 
thread, and I think I'm good.

Incidentally, I unloaded cx18, then reloaded it.  That looks like the 
first 3 lines.  In addition, note that there is no firmware load.  It 
only appears that firmware is loaded when the first client attaches.  
This appears a bit later in /var/log/messages:

That "cx18-0: Video signal:              not present" has me worried.  I 
just reconnected the coax to the output of the splitter, and that feeds 
the bttv card just fine.  Then the "cx18-0: Specified video input:     
Composite 7" would make me think that I'm not looking at the tuner 
input, but "v4l2-ctl -d /dev/video1 --show" gives:

I get a red screen, which I guess is consistent with no signal.

Also nothing.  Incidentally, it's now running at a more reasonable 
resolution:

Starting playback...
VDec: vo config request - 720 x 480 (preferred colorspace: Planar YV12)
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.33:1 - prescaling to correct movie aspect.
VO: [x11] 720x480 => 720x540 Planar YV12


By the way, should I be doing a "modprobe ivtv" prior to "modprobe 
cx18"?  When I was fooling around with it the other night, I noticed 
that loading ivtv first did change the symptoms, and may have increased 
the apparent functionality, though I may also be interpreting that 
wrong.  I notice that there doesn't appear to be any direct dependence 
between ivtv and cx18, though both do use several other modules.  I also 
thought I saw that cx18 used pieces (as in source code) of ivtv, but 
didn't depend directly on it.  Is it also possible that ivtv is 
hurting?  A quick "rmmod ivtv cx18 && modprobe cx18", and the v4l2-ctl 
command above gives the same results.

I think the crux of my problem is the lack of video signal, but don't 
understand it.
Thanks for assistance, so far,
Dale
