[mythtv-users] tinny/scratchy sound with latest SVN build

I recently upgraded to the latest SVN release. (I usually don't have any
issues doing this.)
This time, though, I'm getting tinny/scratchy sound randomly from each tuner
card (three PVR-150). I can switch from tuner to tuner, and get bad sound
about 1/4 of the time.
I'm also getting this in my logs now:

I know this mentions upgrading to ivtv 0.10.0, but I can't right now, as I
don't have a recent enough kernel. (0.10.0 needs 2.6.16 or better, and I'm
running 2.6.16.) I um unwilling to upgrade my kernel just yet, as I don't
have a current backup, and I'm out of town for the week, so if the machine
doesn't boot, i'm hosed.
I tried to go into my recording profiles and change the sample rate from
32000 to 48000Hz, but that box is greyed out. So, I went directly into the
database, and changed the 'samplerate' in the 'codecparams' table.
That got rid of the warning about the sample rate, but the rest looks the
same.
