I have not adressed this but will look into it. I want to enjoy my system
working at least as it is now before I mess with it and potentially do
damage :)

I started investigating Doug's above suggestion.
In doing so, I found that somehow my xorg.conf  was not
using the Driver that I thought it was ...

I changed it from "Driver" "nv" to "Driver" to "nvidia"

After rebooting --- I can now watch LiveTV, I can watch recorded

So -- in my case,  my X freeze, cpu usage issues seemed to be a direct result
of not using the correct video drivers ....

I'm going to review Jarod's HOWTO guide again to see what else I find
that may not be correctly setup.

Thanks to the ivtv and the mythtv developers for a great system,
thanks to Jarod for the HOWTO guide, and thanks to the users on this
list who chipped in and gave me advice and suggestions.
