@Soulfox -- good information, and it is worth mentioning that those converters are generally inexpensive and come bundled with the software you'll need to capture video and save it to a common, digital format. Instructions are usually included, too.
Of course, it might be that you already have the software you'll need for the process. If you don't or if you are not sure, make certain to buy a converter that has software and instructions on how to use it.
And don't worry about the quality of your video card when ripping software. If you have a computer that was made in the 21st century and one that will run the software you'll need for the process, your video card will be more than good enough. We're not exactly talking about cutting edge technology here.
