i have a series of dvds, about 20 of them with 20 hours of footage total, i want to get all the footage on my computer, then burn it onto blank disc. i want to give the origional copy to a friend of mine because he cant walk. any help please? i heard something about DVD ripping software, but i am technologically illiterate and am not sure what the effects of dvd ripping software are. any help would be widely appreciated.
