Switching the PVR-250 to another PCI slot usually solves this; most mobo
manuals will tell you which PCI slots share IRQ's with each other and with
onboard devices. Ideally, both your GFX card and the PVR require an IRQ
each so that they can be bus masters. Devices like USB controllers and
sound cards don't thrash the bus so much and are happy sharing IRQ's with
Failing that, you can manually assign IRQ's to devices in the BIOS.
