[mythtvnz] Schema downgrade

[Mark]

Doh!

After investigating some recent problems I've just discovered that I've
been running trunk from JYA's repositories instead of 0.22.  I
downgraded the packages on the off chance that the databases happened to
be the same but 0.22 is wanting schema 1244 and mine is 1246.

Does anyone know if it will be simple to work out what will be required
to 'revert' database changes?  Guess it looks like I'll finally be
downloading the mythtv source.
