As someone wrestling with the same problem (using a PVR150 and PVR350) I have 
a cron job set up to unload/load the ivtv modules as a temporary workaround 
(and save a bunch of rebooting). I now average only 2 or 3 failed recordings 
per week.

#!/bin/bash
modprobe -r ivtv
sleep 5
modprobe ivtv debug=0x4f
