[mythtv] what's this dmesg output mean?

[Kirby Bakken]

Running a Fusion5 Gold card, and an HD5000 card.  Biostar MB with Nvidia 
6200 PCIe card.  Kernel 2.6.15-gentoo.  Nvidia video version 8178 (and 
yes, GL Vsync doesn't work..  I live with the occasional 'horizontal 
seam'.  Also, I'm running SVN 8605.

When watching LiveTv (perhaps watching recordings, I haven't checked 
that yet), I get this output from 'dmesg':

Other than 'filling up' dmesg space with these messages, everything 
works fine....  Is this a 'mythfrontend' problem?  Or Nvidia?

Also, I posted a question asking for help with getting NTSC to work on 
my Fusion5 card...  I created a 'third' capture card with V4L...  and it 
looks promising, but mythtv-setup messages seem to indicate that this 
'capture card' is still 'configured' as ATSC....  Any ideas here?
