Minimum System Requirements

I was looking at a DVD burner at Costco the other night and I noticed that they listed the minimum system requirements as at least a 700 mhz Pentium III. What do you all think, can you copy and/or burn DVDs with a lessor system? My own pc is marginally better than that (Pentium III 550E o/c to 733 mhz). I can always use the wifes new machine which has a burner but I was just wondering if my old box could handle the load.
