Creation of dvd

I have some video files that I watch on my pc with windows media player.
I’d like to see these files on tv, with the dvd player connected to tv.
How to change the format of these files?
Now, finally, nero vision express seems to work. I have to use it (in this case how? which options I have to choose)or I need to download some other program?
Thank you for suggestions

Well, what format are the files you have now in?

file audio/video windows media

I 'd like to know the difference between dvd-video and dvd-video(+VR).
which one I have to use?
I have to select some option in order to create a file readible by my dvd connected to tv?
thank you
