I use knoppmyth, and I managed to trash my Pc so it wouldn't boot, this is

Drop the Hard disk into another PC then use a live CD disto, such as knoppix

then mount the disk like so mount /dev/hda1 /harddisk, and mount /dev/hda4

once mounted you should then be able to copy the  /var/lib/mysql directory

rebuild the hardware. Reinstall your OS, and mythtv, then with the backend
stopped and mysql stopped copy the datafiles back, and you should then be in
business.

have fun and good luck
