Does anyone use a Book or Media cataloging program they'd be willing to recommend? I'm willing to look at anything, free or for pay.

I've been using Data Crow (found it through SourceForge.com) and have gotten frustrated with some of it's limitations.  Specifically, the limit on methods of inputting new items, on searches, and how I can or cannot change data fields.  The other night I searched by the author J.R.R. Tolkien and it didn't find more than half of his books which I own.  Frustrating.

I'm primarily interested in cataloging my books, but if the program can do dvd's too, that'd be great.  One that can do two or more catalogs would be even better.
