Which is the best way to duplicate a dvd-r ?

[macmithos]

I've authored a dvd on a dvd-r disk using DVDSP and now I need to make 10 copies of that. Should I keep formating 10 times using DVDSP or should I use Toast ?
Using Toast, should I use the "Copy" tab or the "Data" one ?
Using the Data buttom, after dragging the Video_TS and Audio_TS files, do I have to remove/delete the .DS file that comes along ?

You want to make a disc image file of the DVD-R and duplicate that to new DVDs. Toast does this easily by selecting the DVD in the Copy window and choosing Save as Disc Image from the File menu. Then eject the DVD and change to the Image File setting in the Toast Copy window, choose your image file and burn your discs.

This also can be done with Disk Utility but it takes longer.
