Jarod,

My numbers are with a dual display running first on the CRT and
then on the TV without reboot or change.  I have 512MB DDR
2700 and the GFMX440se is 4x on an Asus A7V8X-X mobo.

If your numbers for the XP1700 are correct I seem to be very,
very low.  I can understand why your dual Athlon MP blows me
away (especially w/ the Ti), but I wonder if you could verify
your numbers for the XP1700.

I too intend to try the later versions of the driver [the current
and maybe the beta to see the config tool  ;-) ].  I am just
hesitant to mess up a good, working Myth config.  I started
on 0.7 (?) and have never had any significant problem with any
subsequent Myth or ivtv release (knock wood).  I suppose I'll
have to dive in eventually.  I'm on MDK9.1 and need to upgrade
to a newer kernel for other reasons.  Just have to screw up my
courage.
