You can always just set the database hostname or IP address appropriately as it's only stored in $HOME/.mythtv/config.xml or one of the many mysql.txt files scattered around the file system.  (All config.xml and mysql.txt files will need to be fixed, though.)

Thanks Mike,

The actual hostname of the box has not changed, only the 'internal' (inside myth) from to a real address

Unfortunately, the enjoyment of my current working system is somewhat compromised by the fact that all my wife's old recordings, while available on attached storage, are *not* accessible via MythTV, and asking her to watch '1090_20091123170000.mpg' in the hope that it is indeed last Thursday's Oprah is *not* going to cut it

I'm happy to rename the files and move them into videos, if that were an option, but i can't seem to find a scripted approach to that, either. Hmmm - wonder if I can derive a program name from the file name ....

thanks as always
