I have a bunch of cool action animations from Mixamo, i would like to chain together but as soon as I introduce a new one the character position resets.  How do you get the chained animation to begin where the character's position was at the end of the previous animation?  This has been so frustrating.

I would also like to know that...

To be honest, if i drag the animations one after another into the timeline, the character position wont reset.
But of course, the end and start of the motions don't match. With a bit of transition between them, it get's better.

I don't know if there an easy way to match them without sampling the animations, which would mean a lot of events would have to be edited...

Nope....that's exactly how you do it.  They just need a little transition overlap, and they all start where the other ends.
The problem I have with Mixamo stuff, is I have to use iClone 6.? to get the pipeline to bring things over. 
Did a bunch though....just had to re-install iClone 6 to do it.
Just my 2 cents worth.
