Clark,
Couple of things here.
1. Post the output of mythbackend --version
I want to see if you compiled ivtv compatibility into myth.
2. According to the wiki, "Once the drivers are installed and appear to be
working, you can configure the device in MythTV. For the most part, you
should be able to treat the encoder as if it were a Hauppauge WinTV
PVR-x50/500 card: Tell MythTV that it's an MPEG encoding card"
and
"One slightly confusing fact: On my system, the backend configuration tool
(mythtv-setup) detected both the /dev/video0 and /dev/video1 devices as
software encoders, but attempting to configure /dev/video1 in this way would
not work. Using the MPEG-2 encoding screen, manually typing the device name
(/dev/video1 in my case), and proceeding with configuration worked. Once the
device filename is typed in, mythtv-setup recognized it as an ASUS PVR-416."
Have you done this?
Note: the ivtv driver does NOT work for the card you are using. You just
configure myth to connect to it using the same method as an ivtv compatible
device.
