I'm trying to some the same thing. Trying to fill in some holes in an old vixen seq where I have replaced incans with RGB. Something sounds off on your process, but I'm at a loss at the moment. I'm trying to get back outside and finish some more mounting while its daylight and warmer. I am renaming things to keep them straight. Fixed a couple of things in one of my 2012 sequences and renamed the updated version as 2013 ver1 .... Will be back at this tonight.
