Well I did all this with "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0" entered into /etc/default/grub and still don't have 1024x768 resolution or the ability to change to that resolution. Any more ideas?

So this is interesting. I posted this question on a MythTV mailing list that I belong to and it looks like this isn't an issue of resolution at all - it's an issue of overscan. Apparently all TV's overscan and some allow you to turn it off and some don't (mine doesn't). Moreover, modern TVs can work with multiple resolution inputs and scale them accordingly (in retrospect, I knew this).
You can adjust for overscan in your xorg.conf file as per instructions here ( I'll figure out the details tonight and post the solution (if it works).

It worked. I applied the new metamode by adding the line (in red) below (had to play with it a while) and I now I have everthing visible on the TV.

Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"

Option "metamodes" "DFP-0: 1280x720 { ViewPortIn=1280x720, ViewPortOut=1215x685+35+15 }"
As you can see the input is still 1280x720 but the output is 1215x685. The 35 and 15 simply adjusts the origin (from 0,0) in the top left corner to a point that is visible on the screen (35,15). Then you just have to figure out how many pixels you have left to fill the screen. Be careful not to go too big though because it really messes with your computers GPU.

Thank you to everyone who helped.
