Firewire and USB both have comparable high speed data transfer speeds. The difference is that USB sucks up more CPU resources than Firewire. Using like a movie editor, or some large scale CPU intensive program, USB will falter. Firewire is always the better choice over USB in larger data transfers (DV & harddrive data).
Editing DV and flushing back to the DV. I use iMovie on Mac, and I just go to Export or Share under the File menu. there is an option for Camcorder. This option records back on the camera. With Windows, i'm not too sure...
What are the advantages of using a firewire cable instead of a USB?
And....
Can the Panasonic PVGS150 record back to the DV tape after a video has been edited? And if so, how do I do it?
