Be careful when you have selected ALL that you *only* tick the box for fields whose contents you wish to delete - the first time I did it I managed to delete something important like the IMDb reference number and that is a real ******* if you do that!
Operations can be undone using the undo command under the edit menu. Keith is right in that a batch "get advance info" needs to be undone one at a time. Even though 50 movies might be done in a batch, due to the time it takes to download the information each edit is a distinct operation. (They might also group in batches if DVDpedia is not the active application.)
this is an informal feature request to append the action to Undo/Redo menu commands, like "Undo <action>", so it's clear(er) what's going to occur.
Some actions (delete) are labeled but would it could be improved if a few more where labeled.
The beta now includes: add, edit, multiple edit and drag undo actions labeled.
I too thought that IMDb would always use the reference number to locate a movie, rather than the title.
This is correct. This is why the first time it does help to use the gear button to be able to verify that the correct IMDb number gets associated with a movie. Otherwise DVDpedia uses the title and release year to make the best guess. Once you have an IMDb number then it will always retrieve that movie information, perfect for refreshing the ratings.
I have to rename the movie to its original title, refresh data and rename back.
The plug-in tries to use the AKA search to match titles that are not in the original language. However, the plug-in also looks at the original title field. So if you download information from Amazon.de and can't find any results with the gear button on IMDb due to the German title, don't rename the title but set the original title field.
some titles are almost always left unchanged
This sounds exactly like what you describe a network issue or response timeout. But I will poke around and see if it can be improved on our end.
