I'm not using the sniper, I'm using the WorkPrinter-16. Regarding the cropping, I just traded a couple of emails with Roger at moviestuff, and it would appear that I may need to get a larger gate for the unit for the anamorphic film. It's a wee bit costly if they install it - I will first do some research to see if I can construct (and install) it myself.
By the way, I prepared a film clip of the first 15 or so minutes of the film, with better aspect ratio and some other minor correction. It came out great, but the cropping is now bugging me enough that I'm going to get this gate thing resolved before proceeding. Then I'll start over and recapture everything again. I'll post my progress as I learn more...
