Hi Larry, Thanks for your quick reply and willingness to take a look. I've attached an example file (its a test plate so no copyright issues). It was written using an internal, quite old library, and is fine for reading back by said library (it also seems okay in RV). I'm looking to transition new code over to OIIO, so as I mentioned, if you don't have time to tinker with it, I'm happy to take a stab :)
File can be downloaded from here: https://docs.google.com/file/d/0B7tMukhco9MwVjZWa09ZWW04Vm8/edit?usp=sharing Thanks!
