I have that configuration working.
In /etc/exports:
/pub    -alldirs        client
/pub/video -alldirs     client
On the client side, I didn't change anything to the configuration of AMD.
Simply cd'ing to /host/server/pub and then 'cd video' does the right thing. I 
don't think -alldirs is really needed, but it's there for convenience.
