Dear VVV,
Thank you so much for your feedback!
I'll try to be brief as possible in my response.
1. I have never had any problems with spaces, although aware of possible problems. I tested them before start to use them almost 9 years ago.
2. To reproduce the problem, maybe better idea is to make a new database that consists only a few problematic movies and then send it to you (with my pvdconf.ini and my skin)? Anyway, some movies are:
imdb.com/title/tt0034583/
imdb.com/title/tt0082176/
imdb.com/title/tt0070518/
imdb.com/title/tt0074252/
3. Probably the problem is with IMDb script. But, not only movie, but now I suspect that people are problem too, even before I started to use PVD MOD. I mean, and I'm not sure at all, when we started to use IMDb scripts I noticed that I have duplicate entries for people. It's like some people were imported by nostra's imdb.dll and their duplicates with scripts. So now, for example I have two (sometimes, even more) actors with the same name in database and their filmography is split (to movies imported by imdb.dll and other part with script). If I update both, I get full filmography in both, but links to movies are still split. If I delete any name, I loose them in movies linked to that name. That is why I suggested to send you a small database. Is it even possible to overcome this?
4. I know you won't believe me, but renaming custom fields never worked for me. Of course I tried it once again before started to update database this time, but it just didn't showed up after renaming. My PVD is heavily customized, and I use my own skin (please check the screenshot enclosed), so I'm pretty aware of all aspects of renaming/updating fields. I tried also with IMDb User Reviews/Comments (my custom field name is different), but again to no avail. Simply said - total mystery to me.
5. Fields that I wanted to update/overwrite were: Description, IMDb User Reviews/Comments, Title (not origtitle), Top 250, IMDb Votes, Box Office, Actors, Director.
Kind regards and thank you for your time!
