avi-dvd

[bally]

i've got some avi files that i tried to write to dvd using ulead movie factory after going through the process of changing the files to mpeg and then creating menus etc when i play the disc on my dvd player the picture is blocky,sound out of cinq.where am i going wrong.basically what i want to do is download avi/divx/mpeg then convert them to dvd so i can watch them on a stand alone player
