Successfully burned a dual-layer DVD Movie from source content!
I just got one of those nifty NEC dual-layer 8.5 gig DVD burners and have been struggling with a way to burn a long DVD-video on it. Adobe Encore DVD 1.5 doesn't yet burn to dual-layer discs, but Nero Burning Rom does.
I used Adobe Premeire Pro 1.5 to create the DNR movie, and with the built in Media Encoder, mixed it down to a .m2v file for DVD video (as well as a single .wav file for audio) Then I imported those items into Encore, added menus and graphics, and saved it as a DVD folder containing all the files required to create a DVD-video. Then I just added those files to a Nero DVD-Video project and it worked!
That said, I'm going to be sending the movie to the manufacturer on a hard drive, because the consumer media is too prone to error. It's still very cool that I could burn it.
