A friend of mine (PC user) downloaded the movie Shrek off the net in AVI format. The movie worked fine on his comp, so i asked him to burn it for me on CD. So I brought it home, put it in my comp, double clicked on SHREK.AVI icon. After 10 secs a window pops out saying "you may experience problems playing a video track in SHREK.AVI becasue the required compressor could not be found. WOuld you like to close the movie or Continue?" So, i obviously pressed continue. However, the sound was fine but there was no video. WHere can I find the compressor I need??
