If you have already got the DVD video folder structure with .VOB, .IFO/.BUP files, you could use Nero BurningROM to burn DVD.

1. New a Compilation. Select DVD-> DVD-Video.

2. Copy all the .VOB, .IFO and .BUP files from your prepared folder structure into the VIDEO_TS folder in Disc Content screen.

3. Burn to DVD.



If you don't have the DVD folder structure, but only have photos or videos in other formats, e.g. .MP4, .AVI, etc, you need to burn with Nero Video or Nero MediaHome.
