Using Nero 7 Premium to burn Miro videos files onto DVDs

I run on XP Professional, fully updated, and Nero 7 Premium. I have downlosded videos using Miro with BitTorrent, and have saved the Miro video files onto my hard disc. These play perfectly on my PC.
I want to burn the downloaded video files onto a DVD which can be played by a DVD player, as backup. Nero does not recognise the Miro video files. Please can someone explain whether Nero can burn Miro files onto a DVD?
If so, what exact procedure, steps, do I need to follow?

I downloaded a movie which has a MIRO file therefore NERO-7 doesn’t reconize the file what ca i do plz
