ok my dilema is this, i down load alot of torrents which from my understanding r basicly avis. so i downloaded avi2dvd and some of the movies i try to open on avi2dvd dont have a audiostream. some movies i put in have an audio stream but most dont. i use winrar to extract the files after they r down loaded. can some one give me some advise as to how to pull up the audiostream on the avis that dont automaticly come up??
