Nero Essentials isn't working right and I wondered if there was anything open source that I could use. I need to duplicate a DVD that I have authored - not a data disc a "real" dvd (with vob files, etc.) CDBurnerXP did not have this.

Or, if I create an .iso is that the same thing when I burn it back to my duplicate?

Thanks.

edit: is creating an iso and burning it to a new dvd the same as duplicating a DVD in something like NERO or is DVD duplication something else?

An ISO is what you would burn back to your duplicate.

See this Wikipedia article for a little bit more information:

An ISO image is an archive file (also known as a disc image) of an optical disc in a format defined by the International Organization for Standardization (ISO). This format is supported by many software vendors. ISO image files typically have a file extension of .iso.

Does this mean that if I create the .iso of my master and burn it back to my new DVD that that is the same thing as having software that duplicates the DVD? Is that what a dvd duplicator is doing behind the scenes? –  johnny Jun 14 '10 at 14:30
    
@johnny - yes, that's exactly what a DVD (or CD) duplicator is doing. –  ChrisF Jun 14 '10 at 14:34

Well, it is - and it isn't. As long as you're talking NON-DRM source DVD it is. Add DRM and it's a different story. Commercial DVD duplicators deal with the DRM issues (legally or otherwise). –  hotei Jun 14 '10 at 14:38
    
@hotei - I should have included that. In this case as the DVD is self authored I didn't think it necessary to mention it. –  ChrisF Jun 14 '10 at 14:46

ImgBurn will enable you to create an .iso of a disk and then burn that .iso to many more disks time and time again. This is basically what nero does.

and in response to your edit, yes.

I've always been a fan of InfraRecorder, which seems to do what you want and is open-source.
