I have this issue on my PVR-150, but not the pvr-250 thats in the same 
system.
I thought it sounded like audio emphasis was on, but if I check it when 
its happening, it is still disabled.
As a work-around, I launch this script from my change-channel script. I 
launch it in the background because mythtv sets its recording settings 
after the channel change script completes.
This way, I only need to run it once after each recording starts.

-----------------------------------------
#!/bin/bash
# video_settings1
sleep 3

/usr/bin/v4l2-ctl -c audio_emphasis=0

-------------------------------------------
To tell which version you are using, type dmesg |grep ivtv
the version is at the top

ivtv:  Start initialization, version 1.1.0
ivtv0: Initializing card #0
ivtv0: Autodetected Hauppauge card (cx23416 based)

Hope this helps
