Hello and thanks Ivek. Now I see that I can also import these movies to the new empty database, but if I try to do that into my existing database, it hangs while importing, the record becomes corrupted, and I have to kill PVD, but even when trying to start it again it won't make it since PVD will try to open on this record and hangs again on opening.
So what I do? I rename database for example to Movies.pvdbak, then open PVD which now opens empty, then rename the database back to Movies.pvd, then open it via PVD->Open database, so problematic record isn't selected by default. Then I search the database for the exact name of the movie, so I get single, corrupted BUT NOT SELECTED record in the list. Then I click on the empty space on the left tree view, then use CTRL+A to select problematic record, and then pres delete+CTRL on my keyboard to delete problematic record. That way I can again access my database.
This problem is only for IMDb. Allmovie, Rottentomatoes and FilmAffinity work without problem to import data for these movies.
It's not about IMDb script also, because in new database it works without problem for this movie, so it's something with the database. Do you have any idea how would I start to track the problem? What would you do if you had such a situation?
