Try to work on bottom posting.  Posting replies at the top is frowned upon.

Scan for channels populates the frequency information into the database 
for the channels your provider has.  This is unnecessary for US cable 
channels because their frequencies are standard and hard coded into the 
system so it knows what they are.  Myth knows, zap2it knows, so it is 
automatically configured.  HDTV or other sources do not have these 
standard frequencies (ie: channel 2 = X hz) so they must be scanned for.

It is a MySQL database.  You should visit http://www.mysql.com for 
information on it.  A good tool for manipulating the database is 
PHPmyadmin (google it) which, if you can install it, provides a web 
interface for viewing and editing the database tables and information.
