The 390 card showed up as an option on the additional driver menu after
doing step 2.  I am repeating my last post below the line.
-------------------------------------------

I have made significant progress but I am not done yet. It only took an
additional 4 hours :-)

The goal is DVI and analog audio to TV and SPDIF to amplifier but using the
750ti video card and VDPAU video processing.  The audio worked with the old
6200 video card but the video was crap after the upgrade to Mythbuntu 14
from 8.

1) I left Pulse Audio installed. It was installed by my son accidently (he
did not realize the control panel brought in drivers) but the sound works
fine with the 6200 so I left it.
2) I install the 750ti and updated the driver to 390 I used this method
   1) sudo add-apt-repository ppa:graphics-drivers/ppa
   2) sudo apt update
   3) Then launch Software & Updates -> Additional Driver utility, choose
the new driver from the list and apply changes.
3) Check the driver using lsmod | grep nvidia
4) Check the version using cat /proc/driver/nvidia/version.  It reports
390.87 which is correct.
5) Check pavucontrol (Digital Output - S/PDIF) and aslamixer (Front, Main,
and SPDIF) as before.
6) Ran nvidia-settings and saved xorg.conf.  The file looked incorrect and
the TV still lost video when power cycled.
7) Disable xfsettingsd in the GUI Settings under "Session and Startup":
That fixed the TV power cycle problem.
8) Using Myth Setup search for an audio setting that plays both TV and
amplifier. The existing setting that worked with the 6200 card was
ALSA:pulghw:CARD=SB,DEV=0 Stereo.  I tried all settings.

Results
Audio) I was unable to find a setting that played both.  I could play
digital or analog.  I tired both DVI and HDMI connections to the TV and
multiple settings of pavucontrol.  There are a lot of settings but unlike
before I put in the new video card, none would play both analog and digital
off the motherboard. I could also not get digital from HDMI and SPDIF at
the same time. Just one or the other.

Video) Using VDPAU Slim the picture looks much improved.  VDPAU Normal
crashes the frontend.  That was very disappointing.

Wife) Wife is happy with this setup so at least I have stable hardware
until I can get some help to solve the remaining problems.

Goals:
1) I would like to get a higher version of VDPAU as I have been led to
believe that should work.
2) I need to get digital and analog sound working at the same time.
