[mythtv-users] autobackup of database, and optical disk query

[Mike McMullin]

  I have a couple of questions:

1)  What is the default period for database backups to occour, and what
file handles the configuration for where to put the backup?

2) when the boss goes into her profile and launches the front end she's
getting a query box:
"Select a CD drive"
and the following options:
"/dev/fd0"
"LITE-ON DVDRW SOHW-16935 (/dev/sr0)"
"CANCEL"

  I only have the one optical disk hooked up normally (I do have a
second USB burner that's rarely connected).  How can I eliminate this
prompt?
