If you upgraded your whole system, not just MythTV, then you probably
have new Nvidia drivers.  The scaling done by the Nvidia drivers has
been changed substantially and uses different options on the driver
settings to control it.  There should not be any problems if your
screen is a standard size (1920x1080) but if scaling is normally
required to map 1920x1080 to something else, then you will need to
look at the new Nvidia settings.
