The first thing checked for duplicate matching is programid, however 
those are unique per guide data source, and some simply don't provide 
them.  The second is going to be subtitle, description, or both, 
depending on what the user selected.  Description will almost certainly 
be different.  Subtitle may be different, and some sources may also 
include things like the season and episode formatted into the subtitle.

As mentioned by the original post, his old duplicate matching record is 
largely useless.
