I ran into two strange issues with Leopard on my mini. For whatever reason, importing video via firewire would drop frames. I’ve never seen dropped frames while importing video with firewire, I didn’t know it was possible. It’s possible there really is something wrong with the tape or the camcorder but it seems to play back perfectly on the camcorder. The other issue is a drop in frame rate while minimizing windows. This sounds pretty trivial but it was actually pretty annoying. It was nearly as bad as running OS X 10.3 on a 400Mhz G3 iMac.

Anyway, I removed Leopard and reinstalled (erase and install no less) Tiger. It still wants to drop some frames, but not as many.
