How to burn an iso file into dvd?

Hello all,
I have got an iso file (a movie to be exact) and then tried to burn it into my dvd using ahead nero’s software, through NeroSmartStart, I went to photos and videos and then clicked on burn-dvd-video files, I suspect that this option only accept dvd extensions…so how can i burn my iso movie, If I try to burn like a data file, will it run on my dvd player?

Try imgburn it is free,

That is an image file. Just open up Nero Express and click on “disc image or save project”. Then select the .iso file and click on open. Then burn it.
