My scripts are here - this is a work in progress - I am reworking them
for 0.25 so they may not work perfectly at this time. I have an earlier
version running successfully on 0.24. There is also some testing stuff,
patches, executables, etc.  Look in install/opt/mythtv for the scripts.
Parameters for the scripts are in install/etc/opt/mythtv.
