I''ve had some issues with shared interrupts causing problems. I have
two Hauppage MPEG encoders (a 150 and a 500) assigned to a PV domU and
until I got them on their own interrupts, or at least only sharing
interrupts with each other, I had stability issues. In my case they
were sharing IRQs with my HD controllers on dom0.
Have a look at the xm dmesg output on dom0 when you start encoding, it
may shed some light.
