Well, that was enlightening...

ivtv:  ==================== START INIT IVTV ====================
ivtv:  version 0.8.0 (tagged release) loading
ivtv:  Linux version: 2.6.18-gentoo-r3 SMP mod_unload K8 REGPARM gcc-4.1
ivtv:  In case of problems please include the debug info between
ivtv:  the START INIT IVTV and END INIT IVTV lines, along with
ivtv:  any module options, when mailing the ivtv-users mailinglist.

ivtv0: unable to open firmware v4l-cx2341x-enc.fw
ivtv0: did you put the firmware in the hotplug firmware directory?
ivtv0 warning: failed loading encoder firmware
ivtv0 warning: Error loading firmware -3!
ivtv0: Error -3 initializing firmware.
Trying to free already-free IRQ 19
ivtv0: Error -12 on initialization
ivtv: probe of 0000:02:08.0 failed with error -12
ivtv:  ====================  END INIT IVTV  ====================

Since I don't know where the firmware is supposed to be, I did a find for it 
and found the firmware at:


Hotplug should have been able to find it.  Anyone know why it won't load?

Continued thanks.
