Figured it out.
You need to download the repository .zip directly from github, then utilize the Systen – Add-ons – Install from zip file, within Kodi to install MythTV PVR.
Below is where you can download the .zip file.
SSH directly to you max2play. In the case of the most recent version, I used username pi and password raspberry
wget –no-check-certificate ‚http://janbar.github.io/pvr.mythtv/download/pvr.mythtv-jessie-armhf-15.zip‘
Now that the .zip file is on the system, you can go to Systen – Add-ons – Install from zip file, navigate to „Home“ directory, and select the .zip file for installation.
