I bought a copy of DVD Database X about a year ago, and have been extremely happy with it. Consequentially, I haven't even bothered to look at any other DVD inventory programmes. My old G3 Graphite Imac didn't have an Isight camera, and I was only on dialup, but it was able to find pretty well all my movies. The few exceptions were some Aussie films that aren't available in the US, so I had to add them manually. No big deal. The old Elvis Presley movie "Girls, Girls Girls" caused a bit of a headache though (remember, Joe?) In February I bought a new Intel Core Imac, and now I can fit the whole application on the screen at once. Brilliant. Just like iTunes, you can alter the sequence of the columns and their width, as well as customizing some fields if you want. (I'm sure you'll find everything's covered). You can do searches based on anything you like (Title, Year, Director, Plot, Genre, Actors, etc.). You can also give each DVD a rating out of 5 stars. Earlier this week I upgraded to Version 1.7.1 (with a lot of help from Joe Kusterbeck, the wonderfully patient designer of this software) and the interface now looks even better. There is a cover display option where all the DVD covers are laid out in neat rows , alphabetically. Talk about how to impress your friends.
The only thing I haven't used is the ability to download trailers onto your computers' hard-drive, but I'm happy enough without that. Money well spent frankly.
Joe Kusterbeck, the designer of this programme, has always replied to my e-mails, sometimes within hours, despite the time difference between Australia and the US. He has been incredibly patient explaining things to me in layman's terms, even when it was bleeding obvious to him, but not to me.
I highly recommend this programme for cataloging your DVD collection. I do not believe there is a better one on the market.
