Using a Mac unsure how to convert movie files to burn
 

I am new to this limewire game and new to macs. I have downloaded mpegs, avi, etc. and I am unsure what software I can use to convert then burn these files. I have toast, popcorn, macburn, and dragonburn. Do any of these burn these files? How do I convert these avi, and mpegs? Help!! Is there anyone out there who knows what software will convert these files, then burn them. Because I have a mac, I can't use DivX to DVD software. Help!

if you are going to change a program, example .wmv (or whatever pc version is called) to .mp3, click the item and hit return, should let you rename it and you just type in your desired ending. Then i suggest to use toast, cause i use it and i havent found a problem yet
