you need an analog to digital coverter to bring in your videos. I suggest looking at Canopus advc110, plugs directly to the computer through firewire, no software, drivers to install. analog in and out, digital in and out. Great box. Also, you should be aware that digital video files when capture as uncompressed video/audio are 13 gigabytes per hour. You'll need to capture these files to a separate drive other than your system drive (not on a partition). Also, it will be best to ensure that you don't have any unneccesary background processes going on while capturing (i.e. virus scan.....) do a search for a program called end it all (might be enditall)
Good Luck
