Once in awhile, I'll notice my backend output shows: Can't read vbi data
Would this be harmful to recording?

I had pretty much the same problem recently. A good friend gave me this advice:
You need to look into using the "dmix" functionality of ALSA instead of the deprecated (on 2.6 kernels) OSS sound platform.
Look at http://www.mythtv.info/moin.cgi/DigitalSoundHowTo to see about setting up an .asoundrc. Mostly you download the one he provides and probably change the "device" parts inside it to correspond to your digital output. Also uncomment the appropriate line to pick what you want as "default".
Then type this in as the sound device in myth "ALSA:mixed-analog".
To use Myth's volume control with ALSA it's as simple as putting "mixed-analog" (as opposed to "ALSA:mixed-analog" in the sound device part) in the mixer device setting. I left "Master" in the control part.
In /etc/mplayer.conf, set "ao=alsa:device=mixed-analog"
If you use arts in KDE (which is the default), tell it to use the mixed-analog too. Go into sound system settings, force it to use ALSA, and override the device location and put mixed-analog in there.
Then go ahead and play some Metallica in noatun or Juk while you watch TV or a recording. Listen the sounds mix!
Hope this helps.
