hello, so i have a workout series i downloaded in avi format that i want to put onto dvd's to play on my dvd player. there are about 15 of them that are about 150 MB. How can i put them onto dvd's? Also, i would like to have a menu on the DVDs so i can choose which ones to watch. do i need 2 programs, one to convert the files and one to burn the dvds? which programs should i use? Preferably programs that are free. thanks so much!
