I went with DVD Profiler. It's not my ideal solution, but it's the closest I was able to find. You have to buy both the desktop app AND the mobile app. That wouldn't be such a bad deal if the mobile app didn't suck so much ***. The mobile app CAN'T stand on it's own. You have to own the desktop version in order to use the mobile app. The reason is that the mobile app is really a view-only application. You enter all your data into the desktop, then sync it with the mobile, then you can view it on the mobile.
Because the mobile version is so lame, it hurts having to pay for it as well as having to pay for the full desktop version.
But, as I said, it's still the best I've seen. Until someone actually produces a solid DVD cataloging app for the mobile platform, this is as good as it gets from what I've been able to find.
