____________________________________________________________The only HDV camcorders with LANC control are made by Sony. LANC has nothing to do with video capture though, it's a protocol for camera control.
All you need a NLE (Non-Linear-Editor) on your MAC to capture video via the Firewire (Sony calls it I-Link) connection. If you have I-Movie, Premiere or Final Cut (Pro), you can capture and edit video directly from the camcorder through the supplied Firewire cable.
I have a PC and didn't even install Picture Motion Browser - not even sure what it does. I just capture directly to my NLE.
I this where I reply? this is the most confusing sytem I have ever used. Anyway:
I have had this same experience with capturing video from SONY camcorders so my only questiuon is : Does what you say apply to the SONY HD cameras as well? I hear what you say and may be confusing what they say in the manual with video capture and editing, which is different, I guess.
