ConvertX to DVD3 is an excellent program and you can DL it from most of the torrent sites (I got mine from Demonoid) with a crack for generating a PW for registration.
It will convert avi, divx, xvid, mov, mkv, flv , mpeg1, mpeg2, mpeg-, nsv, dvr-ms, ts, ifo, vob, asf, wmv, realmedia, rm, rmvb, ogm all into DVD format.
