I was having a similar problem at first. I 
finally figured out that, for some reason, one of 
my two tuner cards was using the same IRQ as the 
onboard Firewire ports. Apparently, this 
massively confused ivtv, as I would get DMA 
errors, and then ivtv would unregister the IRQ, 
which then caused the Firewire driver to hang up 
the system.

I solved the problem by moving the tuner card to 
another slot. I'd suggest you look at the output 
of "lspci -v", to see if there are things using 
the same IRQ as your PVR-250.
