U HAVE TO GO TO 3IVX.COM AND DOWNLOAD DIVX DOCTOR WHICH ONLY COVERTS AVI'S TO VIEWABLE MEDIA FOR US MAC USERS. NOT ONLY MUST U DOWNLOAD DIVX DOCTOR BUT ALSO ANOTHER CODEC CALLED DELTA 4PR. U MUST DOWNLOAD THEM CORRECTLY HOWEVER, I'D SUGGEST VIEWING THE READ ME FILE BEFORE ATTEMPTING TO DOWNLOAD U'LL FIND THAT ITS ALOT EASIER. AND TRUST ME, ITS POSSIBLE. HERES A TIP, MAKE SURE TO COPY MACDEC TO UR EXTENSIONS FOLDER, BUT THE WEBSITE 3IVX SHOULD TELL U ALL ABOUT IT. HOPE THAT HELPS
