I suppose you may be right on the VIA chipset thing. I haven't read
anything about that yet, but I also have a VIA chipset (KT133A) although
on a different board and my system reboots with one or two PVR500-MCE.
Works fine with just a PVR350.

I have tried ivtv 0.3.5f, 0.3.5s and 0.2.0-rc3j (0.2.0-rc3j has the
PVR500-MCE support backported to it), all of them cause a reboot even
when I am capturing video with
cat /dev/video0 > /tmp/asd0.mpg
No MythTV is needed for these random reboots to occur.

At least once, the machine rebooted just by having the modules loaded,
no capture involved.

I haven't tried these cards in Windows, so I don't know if they cause a
reboot or not. If they don't, then maybe there is a software workaround
for this issue.
