[mythtv-users] Proper video driver loads, but KnoppMyth reports otherwise

The following error scrolls past on boot:

  KnoppMyth found no multimedia video cards!

That error is displayed on the screen, but is omitted from
/var/log/dmesg for some reason.  However, inspection of kernel ring
buffer (dmesg) reveals the following, suggesting that the driver loads
without problems:
  
  Linux video capture interface: v1.00
  saa7130/34: v4l2 driver version 0.2.12 loaded
  PCI: Found IRQ 11 for device 0000:00:12.0
  PCI: Sharing IRQ 11 with 0000:01:01.0
  saa7130[0]: quirk: PCIPCI_NATOMA
  saa7130[0]: found at 0000:00:12.0, rev: 1, irq: 11, latency: 208, mmio: 0xf3effc00

  saa7130[0]: registered device video0 [v4l2]
  saa7130[0]: registered device vbi0
  
This is the correct driver.  I'm running an AVerMedia DVD EZMaker
frame grabber, which has the Philips saa7130 chipset; (also indicated
by the following snip from the lspci command):

  0000:00:12.0 Multimedia controller: 
    Philips Semiconductors SAA7130 Video Broadcast Decoder (rev 01)

It seems KnoppMyth is not equipped with very robust detection of
capture cards.  The driver for the saa7130 chipset has been included
in the kernel since version 2.6.

So the question is, does the KnoppMyth failure to find the card mean
anything to me, considering I'm loading the proper driver?  

The reason I ask is that MythTV is not yet functional for me.  When I
attempt to watch live tv, Myth (falsely) reports that I cannot watch
live tv because a recording is in-progress.
