We have several PMW-F3's and several Blackmagic Hyperdeck Shuttle 2's. The Shuttle 2's are working with one of our F3's but not with any of the others. We can't figure out what's wrong. When we plug the Shuttle 2's into the HD SDI outputs and hit Record on the Shuttle 2's, it records fine on one F3 but won't record on any of the others. They all worked fine last semester and we haven't touched them since. The only thing we've changed is using a new version of Blackmagic's app for formatting the SSD drives.
