Absolutely.  Go to the movie to edit it, click on cast, click on the cast members name (eg. Burton) then select find cast member, then edit cast member.  Ype in correct birth date.  On the main window which lists the cast members if you double click a name it will open a window which will allow you to search the web for pics.  If you do not want to search out your own pics you can go to this thread http://www.invelos.com/Forums.aspx?task=viewtopic&topicID=287443 and use this really nice pre-made database.  Complements of many contributors from DVDP.

Quoting FUBAR:

Quote:
All 3 versions show Richard Harris as 1925.  Perhaps you need to refresh your profiles.  Yes you are able to edit any DVD as long as it is done in accordance with the contribution rules.  Check around the forum for all sorts of readily available info, particularly in the Contribution Section.

The original poster is talking about Richard Burton not Richard Harris.

There does not appear to be any accepted birth year contribution for Richard Burton so the attached birth year can simply be deleted. (See: Here)

Sorry, have no idea why I said Richard Harris (except maybe going senile).  I meant to say Richard Burton is in all three versions listed in DVDprofiler of Becket and his Birth Year is 1925 in all three versions.  Due to this, I think the topic originator should refresh his profiles.
