I'm using the FS-4 Pro HD. In the quicktime mode it took in a 45 second clip in about 5 seconds or less.
In raw dv it brought the clip in just as fast but the media show it was missing. I re-imported the same raw dv clip and it poped in instantly and was usable.
media SW only version 10.2.1
I bought the FS-4 Pro HD for my portable Avid Express Pro. because it records native Avid DV files and they can be dragged right in to the bin instantly and play from the FS-4
