Burning mpeg to dvd disc


My friend has the latest version of Nero, which he bought to burn video files on.

He has saved his videos as mpegs, but on opening Nero it asks you to place your files in the video file, and the video must be in one of 3 formats - one if I remember is iso or something like that!
None of these 3 formats were in mpeg format?

Can anyone tell me how I can burn to a dvd using the latest version of Nero?


Jged :confused:
