Don't have that model, but the NVDS65 which uses the SD memory card for stills. Is this the same for the 17B?. As far as I am aware you require the software but have never tried it. Always take the card out and use the card reader if using the SD card.
As far as capturing video to your PC - you will need a Firewire connection. Then your camcorder should be recognised in the video editing software that you are using. This will enable that programme to capture your video for editing.
