No, I haven't figured out how to do that yet. Though
I do have a TV connected to the output of the pvr-350
card, the TV screen remains blank.

My first attempt at setting up the box was with 
an nvidia agp card.  Selecting watch TV always
locked up the box hard:  no kbd, no mouse, no 
ssh access from the outside.

The solution ended up being to flash the bios,
but before I got to that, I'd removed the add
in card and started using the onboard savage
device.  

That being said, I did try it again with a 
different agp card (ati this time) and an
ati pci card.  The box didn't lock up, but
mythfrontend crashed after a couple of
minutes of bogging down the box (sluggish
jerky mouse, waiting for ages for a kbd
key press to do anything.

Would my problems with the savage driver be
a bug that I should report or is driving a
signal from the ivtv card simply outside the
capacities of the savage h/w?

I think what caused the problems when testing
the agp and pci cards just now was related
to the IDE interface and IRQ.  lspci -v
reports the irq of the IDE controller as
being 255 which I believe is not a valid
IRQ.  When I tried to shut down the box
after both failed addon card tests, I got
io errors to sda6 which is the partition
that recordings get saved to.

Thanks for taking a crack at this,

dave
