This may be related to the issue in the other thread regarding the IMDB Movies plugin.
I'm finding that when I'm in People View and use IMDB to import an actor's filmography, it doesn't always pick up every film listed on the IMDB website. It may only pick up a handful, or sometimes none at all.
The IMDB People plugin always used to work fine, I'm not sure at what point the problem started. I've usually been using it to update existing entries, and have seen it add a film or two most times I run it, so didn't notice the problem until I ran it on a few actors who didn't have much of a filmography to begin with, and saw the imported filmographies were smaller than the ones on the website pages.
I'm (still) using PVD version 0.9.9.21, with version 0.3.0.18 of the IMDB People plugin. In Preferences, the IMDB People plugin is set to import filmography (fully checked, not filled-square checkbox), and "merge filmographies" is checked.
