I had no problem recording 1080 24 using psf on out of sdi. But I have a shoot tomorrow which really should be 720 24, and I've tried every combination of setting, 3:2 pulldown on, and Nano does not detect a video signal, EXCEPT once. At one point in an hour of messing with it, nano actually displayed 720 23, but after I happily powered down and powered up again, no luck, and I've never gotten it to work again. Is this a bug, or am I missing something here?
