I'm thinkin about picking up a dvd drive for my computer. heres my question. Is it REALLY necessary to get a hardware decoder card? Is there a noticable difference between a software and hardware in overall quality and framerate? I have a decently fast system, so won't a software decoder do just as good? I'm not looking to do tv out stuff, I would only be watching movies on my pc. Thx for all replies in advance!
