i was thinking that the imdb id would be a good field to bring in...
If there is no standard field for something you want to include in your database, you can create a custom field. See
Preferences - Movies - Custom Items.
on the first i get to choose the fields and the order...
You need to configure the Excel import plugin at
Preferences - Plugins.
just tried to import a directory, very cool that you do some filtering on the directory names, but it still only gets a 50% hit rate from imdb.
There are two issues here. First, you need to understand the file scanner is using the regex specified at
Preferences - File Scanner. The default regex are not likely to be 100% accurate—especially if you have inconsistent or unusual file pathnames. Second, the import plugin can't do anything more than execute an IMDb search. That is, if you entered the same data manually at the IMDb website, you'd get the same results. Obviously, the title needs to be correct (it can be the original or any valid aka). But, since movie names are not very unique, having the year as well helps in getting direct hits—or at least narrowing the choices.
for big imports (i.e. getting started) it would be much better if it did all of the downloading and remembered the possible choices
This has been suggested by a number of users. Having built my database, I don't find it much of an issue. When I'm adding a handful of movies, I usually have no difficulty finding other things to do with the database while an update is running. When updating a large number of movies, you should be running two passes—one in silent mode, and another with silent mode off to update the ones skipped. The waiting is not so bad when your input is required for every movie in the batch.
will pvd export files for wmc?
Why would you want to? Use
PvdImport to pull the data directly from the PVD database into MC.
can i export to mymovies.xml files
I suppose you could—by creating an export template for that purpose. Some users recently created one for XBMC—it might be similar.
