Create a disk image. Any files will be rendyou have exported in the correct opefully ered once (hmpeg 2 dvd format anyway and will not need to re encode it). Then, you can burn additional copies from that disk image.
I use a P4 3.2 GHz ht processor and 2 GB ram, and a typical render time for a basic video timeline (no complex effects or color correction etc.) would be about 2:1.
