Converting xvid to dvd-r

Hi there,

I need some help with this. I want to convert the xvid episodes of a certain series into dvd-r so that I can watch them on my DVD player with included subtitles. Right now if I burn the episodes to a DVD they show up without subtitles, you know how it is. I have all the needed files on my HDD, I just need help on how to convert them. Is it even possible for a newbie like me?

Any help will be much appreciated.
