That's a pretty old version of ECDC and from what I recall, it was full of bug unless you install a ton of updates that were eventually released. About the time they got it "sort of" working, they dropped the product and we started all over with ECDCV4. Unless Roxio has grown up, they (or Adaptec) never did release a version of their software that was useable at release. When I could, I tried to upgrade to the current version when they announced a new one would be coming. By that time they usually have the major bugs fixed.
Anyway, I think there were some funnies with ECDC3 and Win2K. Check the Roxio web site & their support area for pointers. You may find that they don't have any info there now for v3, though.
