It sounds as though you need a way of connecting your camcorder to the PC. For one example click here
You may prefer a video capture card (Firewire) if your camcorder supports it.
There is another issue though. How much room have you on your hard drive? Because transferring video files will eat hard drive space. Further, if your hard drive does not have at least one partition formatted as NTFS, you will be limited to a maximum single file size of 4GBts. This equates to about 15 -30 minutes of video, depending on the settings you select. The lower the quality, the longer you can record to disc.
