Series/Episode conflicts

How do users deal with a TV series when the series on the box doesn’t match with the series as listed on other on-line data-bases?

For example I have “Alarm Für Cobra 11 - Staffel 9 Episoden 74 - 81” on the RTL box but wiki lists the content as beloning to a different series and has them against another series (differnt to both wiki and the box) and the IMdb has yet another listing.

All I want is my dvd to be in the collectoz db with the correct episode listing (episode/series number).

Has anyone come across this with their collection?
