TV series incorrectly listed in plex, how to fix it?

So anyways, I never seen the tv series Firefly, Plex gets its info from TheTVDB and that site has 2 listing for it, Aired on TV and DVD list, I have the show as its listed on DVD and even named each episode via the metadata in the file, but plex still shows it as how the show aired on TV.
I do not want to change the agent to personal media for the entire TV show database, just the one, or be able to link it to the dvd listing from TheTVDB instead of the aired on tv list, is there a way to do this ?
I know other programs have the option to just input a link from IMDB to add a movie or tv show, plex has nothing of that nature from what I have seen yet, hopefully future updates will has this unless I am just missing this option somewhere.

Yep that worked, thanks much.
