DVD / Windows Help

[Go Terps]

I know I'm a little but I am just getting around to getting a DVD drive for my computer... I have a question... how does this work... I have Win XP and have read that you need a separate DVD decoder card or software... what does this mean for me... I have no idea... I'm pretty sure most of the people here have DVD drive and some with Win XP... could someone please fill me in... thanks
