To start over from scratch with 2500+ movies would be daunting. It takes anywhere from 15 to 45 minutes per movie to properly set up a video. No, I don't even want to think about that. I would prefer to spend more on hardware, but as it is now, I don't know that would do any good.
I wasn't having any problems with their 8.x version, only after "upgrading" to 9.1. I would go back to the 8.x version, but I got the impression that would require having a backup database from the 8.x version. I do still have one, but it is a copy, of a copy, of a copy, etc. and even if it would work, it would mean not having lost all of the entries that I made since then, and that has been hundreds.
