5.1.n or 5.2.n? Did it work for you on the previous firmware vesrion? Nick and Doug are having timecode issues with Dragon. I just tried 5.2.16 with my SB-T and TC, Gen, and Sync all light up green.
both, started with 5.2.16 and thought maybe is a firmware problem, so loaded 5.1.51, but still nothing, no idea what the problem could be
