If you'd like more details, just let me know.

> 2) Which nvidia drivers are you using?

Version 5336 on odin, bragi, cerberus, thor.
Version 4996 on freya, erato.

No specific reason for 4996 on freya and erato other than they are my
wife's systems and I've been a little lazy about getting them updated.

No only system doing TV out is bragi and I'm using the composite output
on it.

APIC is enabled on odin and freya, both show the nvidia driver at IRQ
16.

The others all show the nvidia driver on IRQ 10 and are sharing that IRQ
with something else.  In most cases it's USB.  However in bragi's case
it's the SB Live, and in thor's case it's the firewire controller and
network controller.

I normally start eliminating variables.  Have you ever had the lockup
outside of MythTV?  Have you tried running X on the box with a window
manager instead of MythTV?  Is the box responsive to anything when the
lockups occure (remote ssh connection, etc)?
