I don't know about the HVR-1600 but with the PVR cards that use the
ivtv drivers you can adjust those settings in the actual recordings by
going to live tv and hitting the 'G' key (I think) and it will let you
cycle through various picture quality settings for the ivtv drivers.
If you aren't recording analog then this is irrelevant. As for you
nvidia-settings they aren't normally restored after reboot. I thought
in mythbuntu they had it setup to restore the nvidia-settings at boot.
Check the file /usr/share/mythbuntu/session.sh. Mine has the

 #if nvidia settings are saved and nvidia drivers installed, load them
    if [ -x /usr/bin/nvidia-settings ] && [ -f ~/.nvidia-settings-rc ]; then
        nvidia-settings -l

I am not where this file gets called from, but I am pretty sure that
mythbuntu is setup to run that script at boot. You may want to check
and make sure that .nvidia-settings-rc is being saved in your home
directory. It is saved there automatically when you exit
nvidia-settings. Make sure that  you are running nvidia-settings as
the same user that is logged in and starts mythtv.
