Great fun, Vern!!!
Morphy, and others, here is a rough summary:
1) Load your character
2) Create a new Action
3) Right click on Action and choose New/Motion Capture Device/BioVision BVH File
This will create a new shortcut called 'BioVision...'
4) Right click on this shortcut and select Capture Sequence
5) Navigate to your BVH file and select it. This will load it into your action and will populate every frame in the timeline for the length of the sequence.
6) You will need to turn on your constraints in the pose slider window now.
7) Scale and translate the BVH rig to match your rig as best as possible and then start constraining your rig to the BVH bones. Most constraints seem to be translate to and orient like but use what ever works for you. There will be some trial and error while you get used to how everything is oriented. Scroll through your action to test it but try to confine all your setting up to frame 0.
8) From this point you can start adding your own tweeks to the animation such as toe bends, finger poses, facial expressions, etc.
That's the basics and should get you familiar with setting up BVH files for your characters. Hope I didn't miss anything out.
