AVI TO DVD SOME MOVIES COME OUT GREAT OTHERS LOOK LIKE CRAP

hey whats up guys? ok heres the deal. i am pretty new to all this stuff, so i am hoping someone will be able to help me out. i have downloaded a couple of movies and used dvd flick to transfer the avi to dvd, and then imgburn to put them on disk. i am a big fan of dvd flick, and the first few movies came out great. but the last couple of movies have come out very pixelated, pretty poor quality. i havent done anything differently, using the same blank dvds, and i know i cant bitch about free movies. but i am just curios as to why this is happening? do certain avi types transfer better to dvd? is there something i should be looking for when i download the torrent?
