I am not sure using any of the several graphics driver PPAs is a good
idea.  The PPA drivers are less stable than the ones in the main
repository.

No, the autoinstall option frequently chooses the 340 driver when it
should choose the 304 driver for older cards.  It is better to use the
GUI to manually select the correct 304 driver.  In Mythbuntu 16.04,
the GUI is found by running "Applications" > "System" > "Software
Updater", letting it download the updated package lists, then clicking
on "Settings", then on the "Additional Drivers" tab.

MythTV+fixes from the MythTV PPA is pretty stable.  It has fixes for
bugs discovered after the packages in the main repository were
created.  It is normally recommended to use the fixes PPA.
