[mythtv-users] Question regarding PVR-150

Over the last 2 weeks, I have migrated both of my mythbackends from FC5
(x86-64) to Centos-5 (x86-64), patched them, upped my svn trunk revision
on them, and did the DD->SD conversion successfully.  So now I'm just
ironing out the bugs...

While I've gotten most of them, one in particular is really annoying.
I'm getting the following error in my backend log:

2007-08-25 21:00:03.495 MPEGRec(/dev/video0) Warning: Audio sample rate
32000 Hz
                        is not supported by ivtv driver, using 48000 Hz

And recordings coming from the card are getting "chipmunked".  It's not
too hard to figure out why... So taking a cue from the list archives, I
edited the db settings to make it say 48000 instead of 32000.  That
stopped the error, but not the chipmunking.  (I know that I should
probably ask this on the ivtv list, but since its myth giving the error,
I figured I'd ask here first...)

Any thoughts?  This wasn't happening on FC5...

Distro is Centos-5 x86-64 with kernel 2.6.18-8.1.8.el5

ivtv version is from atrpms, version 0.10.5-130.el5
	firmware 20070217-13.at from atrpms
ivtv kernel driver is ivtv-kmdl-2.6.18-8.1.8.el5-0.10.5-130.el5

mythfrontend --version yields:

Any ideas?
