Allow episodes to have multiple series
- Permit a many to many relationship between series and episode; an episode may have more than one series and a series may have more than one episode.
- Requires the addition of a linking table (e.g. series_eps linking series and eps)
- Requires the double series entries in the series table to be identified and turned into single series entries linked to the same show.
- Code which depends on the existing database structure will need modification. The use of database views will assist with this transition by hiding the full (possibly complex) queries
