If you are seeing black in the capture window something is set wrong somewhere. Throw out preferences, set up your new show using the 1080 60 or 50 HDV settings, whichever you shot in and try to capture again. By the way, I hope you aren't trying to capture to a single internal drive on your powerbook.
Also check to see that in your capture window both "audio" and "video" are selected for your capture, and set up a new bin and "set logging bin" to that folder. I've had trouble on batch capture if I don't set a "logging bin".
Good luck!

BTW, I've captured from a FX 1 no problem so something is amiss with your work flow. And yes, there is a "search" feature at the top of the cafe window.
