After exporting some pz2 clips from Mimic Pro, I was able to import those clips into C7 Pro without any difficulty - the lip synch animation looked fine.

I haven't been able to capture that data in an NLA clip however.  I don't get any error messages along the way - but after Selecting the Root of the Figure, going to the NLA tab, saying Create Master Clip, the keyframes don't disappear from the timeline and the saved clip doesn't carry any animation data with it.

Any ideas as to what I'm doing wrong?
