I'm not quite at a thousand yet. I've been doing it slowly over time, but yes - I did have to enter each one manually (and each one is about 4 clicks). Now that I'm caught up, it's easier to add 2 or 3 a week, depending.
Have a fast question for you. New to the boards (registering, anyway) and noticed you have over a thousand BDs! How did you get that number to appear? The only way I found to do that is to check each BD individually under the MOVIES heading, and each time doing that is four clicks.
