You are off by 2 because setting the filename of a player also sends a 
"playstopped" message. You'll need to bracket setting the filename with 
"lock messages/unlock messages" commands to block the extra playstopped 
message that gets sent.

But brace yourself. There is a discussion going on right now on the MC 
list about playing files serially in a player. While the Rev IDE 
receives the "playStopped" message just fine, standalones built for OS X 
do not. It's a bug. If you are only building for Windows there's no 
problem, since the bug is only in OS X.

My work-around involves including a calculation like this:

    -- set the player filename, then:
    put the duration of player "mp" into theDur
    put (theDur/the timeScale of player 1) into theSecs
    start player "mp"
    send "movieStop" to me in theSecs seconds
And then replace your "playStopped" handler with a custom message 
handler, like this:

on movieStop
   global gCurrentMovie, gMovieTally
  --if there is only one clip listed in fld "goodFiles", then stop:
  if the number of lines in fld "goodFiles" = 1 then
    set the hilitedline of fld "goodFiles" to empty
  else  -- line 2 or greater
    get the hilitedline of fld "goodFiles"
    if line it + 1 of fld "goodFiles" = empty then exit movieStop
    set the hilitedline of fld "goodFiles" to it + 1
    put line it of fld "goodFiles" into gCurrentMovie
    set the filename of player "mp" to gCurrentMovie
    set the currentTime of player "mp" to 0
    put the duration of player "mp" into theDur
    put (theDur/the timeScale of player 1) into theSecs
    start player "mp"
    send "movieStop" to me in theSecs seconds
  end if
end movieStop
This is a kludgy workaround until the bug gets fixed.
