Thanks Ivek.
The best results, however, will be achieved when nostra finds a way for a PVD's imdb plugin to log in to a site.
Then, I'd recommend to set these site preferences for IMDb, when logged in:
"Title display country" - Local country
"Title display language" - English,
for which imdb seems to has corrected 
earlier bug
That way, instead of original title, the English title will always be shown on the imdb, and imported to a PVD "Title" field, 
when there's no local country's release title for the movie on imdb.com. The original title will be imported to a "origtitle" field, in any case, 
when there is one stated on the main page.
Nostra, please let us know when you find a way for imdb plugin to log in.
