It would be very helpful to know what exactly you are trying to do (what is the source of your recording, what format are the files you have - assuming you have some files already recorded, etc., etc.) along with what you have tried so far AND some information about which version of MEP and the spec of your computer!

Sorry to ask so much but your question is very vague, unfortunately.

However, if we take your question "as is" the strict answer is "you can't".  Recording directly to DVD format is not possible.  What you have to do is "Export" or "Render" existing video to DVD once you have edited it in whichever version of MEP you have.

So, help us to help you, give us MUCH more information.
