Re: Speed up Adding Movies
I agree with Eric. This feature is long overdue for implementing. Batch update should mean keep going without any user interaction all the way to the end and then provide a log report to show what happened. Jef's tip is excellent for ensuring that you get exactly the results that you want on auto update, however, unless I'm wrong, it does mean manually going through your entire collection on IMDB and copy/pasting each ID into a text file.
If you don't follow that route, you will need to go through all your collection anyway to ensure that each movie was created correctly. I'm assuming that you selected the option, "get first title from search result" which should mean most stuff gets updated with something. Also, it's worth reconciling the number of files in your movie folder with the number of films in the database, because it may well miss some with odd file types like m4v.
On a positive note, you should only have to go through this once (my database has survived a few years and updates from v3-4-5) and I found the process easier with this program than any of the others I tried
