Jason,

Being a complete novice when it comes to movie making, I decided to finally take the plunge.  First, I tested your commands on the prototypical 1nmr file which worked great with the commands that you had described.  However, when I tested the same commands on a 212 state DCD file the results were mixed.

What worked:

load structure.pdb

#load trajectory with 212 states
load structure.dcd

mset 1 x212

mview store, 1, object=structure, state=1
mview store, 212, object=structure, state=212

This produced the movie that I had expected (though, it is not different from simply issuing the first two commands pressing play)

What didn't work:

load structure.pdb

#load trajectory with 212 states
load structure.dcd

#Use half the number of frames and hope that states get skipped by PyMOL
mset 1 x106

mview store, 1, object=structure, state=1
mview store, 106, object=structure, state=212


When I play this movie, the first frame corresponds to the first state but all other frames display a blank image.  Perhaps I'm misunderstanding the commands here?  Any clarification would be greatly appreciated!
