I have a Panasonic DVX100B. I have a Firewire port, and a Firewire cord on my PC, etc. So how I do I upload footage that I've recorded? I've only been able to plug my camera in to the computer and record footage off my computer using software like Vegas. But I want to upload things I've already recorded. How I do I do this? I know it's possible, I've seen footage of people skateboarding captured with the DVX100B, and I assume they're not in the skatepark with their camera plugged in to their laptop in the middle of a skatepark skating-bowl lol. So how do I upload previously recorded footage on my PC? Thanks.
