how do i convert a xvid file onto a dvd

XviD what? AVI, OGM, MKV, MP4?

The fact that it is XviD doesn't really matter (as long as you have a recent XviD build installed), the container format is far more important.

If it is an AVI then you convert it the same as any other AVI, if it is an OGM then you convert it the same as any other OGM, etc.
