converting avi files to mpeg

My friend sent me the torrent files for rain man dvd. he then said that i needed winRAR to extract the files so i did. Then he said that i needed to convert the avi files into mpeg so i downloaded winMPG video convert and when i try to convert the files it says Mpeg1/Mpeg2 should have audio and video stream what do i do and how do i convert the files? please help

 

use the following tools and guides to make a DVD from AVI and the like:
1. winrar
http://www.rarsoft.com/rar/wrar320.exe
It doesn't expire, all that happens is you get a 'Nag-Screen' which pops up when you open winrar, saying licence has expired, or something close to that, but you can still use it ok.
a) OK, you open the .rar file or open any one of the rar files, then you extract it. Rar files vary in format, they can be .rar, .r01, .r02, .001, .002, and etc... -- What I do is usually extract the .rar file and if it doesn't exist, I open the last highest number rar file and extract that.
b) This should extract 2 files for you. A .bin and .cue file. Once, you have your .bin and .cue file, you should delete those rar files now to free up some space.
