Personal Video Database

why when i delete a movie it doesn't actually get deleted from database?

i delete movie and when i add it again it asks if i want to add the movie that i added before or if i want to add a new one.
if i select the new one it finds nothing(says no movie found).
i noted that when i select the new option ,then  in lower status bar of pvd (that shows the internet queries) that the search from imdb is done without the search quote (with an empty quote for search )
and if i select the added before movie it gets it from the imdb page of that movie (without searching for it).it load the old movie complete with customized poster that was supposed to be deleted.

but if i search for a completely different and not added before movie (that doesn't show me that dialog to select the old movie or add a new) record the queries at bottom of pvd contains the title i requested for search.
it seems that  imdb plugin is broken in this area.(i cant test other plugin to see if thats true for them too)


the weird thing is that when i want to add "Emanuelle in America" http://www.imdb.com/title/tt0074473/ and i search for 'Emanuelle in America' it asks with a dialog if i want the new option or the already added and deleted entry .if i select the new option it finds nothing .if i select the deleted entry it load the deleted entry complete with poster added from amazon even though i have not selected the poster option .
now the weird pat is that if i search for 'Emanuelle America' (without the 'in ') to fool pvd to think i want o add a different movie it doesn't find the 'Emanuelle in America' in its list of found movies.
plz help.

i usually use imdb but this website http://www.themoviedb.org that pvd has a plusin for, has good info too and its open database(user driven) so its hope for it . bbut when i use the plusig it doesnt found movies .i havent tested it for all movies but for example this movie "Mansfield Park" 2007 has this imdb page and themoviedb  http://www.themoviedb.org/movie/16236 page but themoviedb plugin says 'no movie found'.

what gives?

hello
i found this good program and i hope to use it to replace extreme movie manager9 a good app but commercial closed source and not easy to use)

i have this problems

1. how can i disable some plugins .not delete them just disable them,cause i use less that half of them.
like , i use only english plugins and there are a lot of russian pluings( which i suspect is this program creator language)that i don't use at all. if there is no way to disable them is there any way to delete them?

2.i configure imdb plugin for movie info to get aka search result and it stay s that way but when i do the same to imdb plug-in for polple info both imdb plugins setting get reseted to default.(maybe a conflict of names for these plugin settings?)

3. what is the deal with selecting boxes modes. i mean they have 3 mode :empty ,filled with green color, a tick. what is the difference?( maybe update or rewrite but which one  is which)

4. when i use one plugin to get info for a movie (say imdb plugin) and then use another one to get more info for the same movie it rewrites the info( i think because i see more info like a longer description of movie but not not a trace of imdb description).should create and use batch mode plugins to get all of info from both   sources? or can i use the update/rewrite mode of selection boxes for doing this( this is after i get to know how in answer to my last 3rd question.)

5. what is the "merge filmography option in plugins page of preferences?is it for my 4th question?

a somewhat detailed answer would be very appreciated.
