How to burn a dvd from flash drive

[kirk_66]

Hello, can anyone here assist me in burning a DVD from my "thumbdrive" or flash drive. My DVR can't play it, and I've tried downloading nero with no luck. This is MY 4-minute video for a client. Any answer greatly appreciated!

is the file on the flash drive an ISO?
with windows 7 there is a built in tool just double click on the iso file and insert a blank disk into your optical drive.
