Hi,Read this Burn CDs and DVDs on Mac - Apple Support. Note that you won't be able to burn movies that you have purchased from iTunes store because of copy protection.

What goal are you trying to achieve? If you simply want to drop a video file onto a DVD, then Jimzgoldfinch's information will work. You will end up with a data disk with a file on it, the same as any other disk your computer reads as just a disk of files.
Many newer DVD and Blu-ray players can read MP4 files and play them from a data disk, so it will still work.
But, if you mean you want to create a DVD that is the same as a commercial movie disk, you cannot do that using only the OS. You would need something like Toast Titanium.
