I have a JVC 270. It has digital in and out, but no analog input. All of the sony models that I have researched have analog and digital input. The helmet camera I have has the rca jacks, but my camera doen't. The camcorder I have accepts the 4 prong digital firewire cable (av cable?). Doesn't helmetcamera offer their camera w/ a choice of either an analog or digital connector? If so, does the digital helmet camera have the four prong firewire cable that I am looking for. There are no adapters offered for rca to firewire conversion. I am wondering if I should take the JVC back for a more user friendly Sony, any suggestions? Don't get me wrong, the JVC is a sweet ride. It offers comparable picture quality, if not better, and more manual operation than the "point and shoot" automatic sonys and a about twice the zoom for about $150 less, but I am a little skeptic about the helmet camera and video editing software compatability. Thanks for any help or direction on where to find it!!
