ChrisD's animations are great. One thing I like about his stuff is that each animation file is pretty much just one action. Throwing, running, jumping, etc...which is a lot easier to work into your own work or sets than BVH's which are are a long series of several actions in one file.

ChrisD's stuff is also great to learn from. After you load up one of his animations, study it, maybe start cutting out some of the keyframes and try to reverse engineer it. Load an identicle character next to it and try to reproduce the action yourself. It can teach you a lot about good human and animal movement.
