you will need a Blu-Ray disk burner and software, such as Toast, to do it.
However, if you are just trying to make a regular DVD disk that will work on a Blu-Ray player then you can do so from iDVD or, again, Toast.
You can also burn disks directly by inserting a disk, waiting until it mounts on the desktop, dragging the items to it and then ejecting it.
The disk will burn before being ejected.
Did you know that there is a whole series of Mac forums here on CNET?

One of the best French door fridges we've tested
A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
