Export as a self-contained movie from your editing time-line, and then compress to m2v. The bit-rate will depend on 1. the length of your movie, i.e. for a single layer DVD5 or double layer DVD9. 2. wether you want to duplicate or replicate (a matter of reflectability) and use of constant or variable bit-rate. Read up on this stuff and you will arrive at the solution for your project.
