What size is your file(s)? If it's a dvdr and in vobs then you will need Nero to burn onto a dvd. If it's an avi (divx/xvid) unless you have a divx dvd player you will need to encode to dvd format. Again you can use Nero which gives ok results but for quality encodes use an app called The Film Machine which you will also need Cinema Craft Encoder (CCE) with it.
