Though you described the right configuration, the settings aren't being
applied. Note that with NVIDIA (and many other) drivers, if the
monitor/TV reports EDID info, it's often not used.
More likely, though, you'll find a section in mythfrontend Appearance
Settings on the page "Screen settings" that's labeled "Monitor Aspect
Ratio". This appears only if you're using Xinerama or (due to a bug) if
you're using a very new version of X server. If that setting is there
and you have two (or more) displays, just set it to 16:9. If you're
only using one monitor and the setting is there, try setting it--though
it shouldn't be there and a patch (to be applied "soon") will fix the issue.
