Personally i would use the "seat of pants" method. (Not suitable for
novice installers)

ie. If you store all your recordings on a separate drive / partition
then you dump your full database to that partition, with anything else
interesting like ssh keys.

Then go forth, and re-install making sure not to reformat the recordings
drive / partition.

Once the OS is install get mythtv built / installed, restore database,
cross fingers and start it all up.

If it all goes wrong you get to restore from backup.. ;-)
I did mention this was the "seat of pants" method and contains no
backup instructions at all...
