What exactly are you trying to do? I'm unwilling to answer random 
questions about the database schema or data without knowing what, 
specifically, you want to accomplish with your custom rule. Or, put 
another way, if you don't understand the data and the schema, there is a 
non-zero possibility that the approach you're hoping to use to 
accomplish something is not ideal, which means that I'm likely to be 
wasting my time writing out information to answer general "fishing" 
questions.

There is. :)

Note, also, there are some example clauses available for custom 
rules--such as, "Re-record SDTV in HDTV (disable duplicate matching)".
