I want to start a web site were clients browse and select MPEG2 files for a custom DVD and then click "Download to DVD" and the custom content automatically burns to a DVD, is this possible? Appreciate any advice.
Perhaps if you engineered it in reverse. Create an application that can be downloaded from your site. That app would then browse your media files in a custom browser and download them. Then when they're ready, they'd click burn.
But I don't know of any way to create a DVD with a web browser and a DVD burner. If you've ever used DVD creation software there's more to it than burning a media file to a disk. There's menus and stuff to create, so something would have to create all that.
Perhaps you could develop a server-side app that collects their choices, creates a dvd disk image, and then that image could be downloaded by the user. They would have to then manually burn that image to a DVD. Not sure if you could make that happen automatically without putting some sort of application on their machine.
