I had this issue with a PVR500 (With Samsung Tuners) on version 4.X of the IVTV driver. I'm currently running version 1.0.0 on a stock Ubuntu kernel (2.6.22-14-generic). I've only run it for a day so far, but I haven't encountered the issue since then.
One thing that would >always< fix this issue for me was running "/usr/local/bin/ivtvctl -d /dev/video1 -q 0" (Assuming Tuner 1 was recording). I eventually ended up writing a script that would run this command for the tuner about 5 seconds after the program started working. You might try it and see if it will fix your issue every time.
