Serato dj 1.9.10 version was the best for videos and the reason I say that is because it played my compressed avi files after I installed a codec called Persian. When I updated to the first Serato dj pro it stopped playing the avi files, and I'm not on the latest Serato dj pro and its the same thing. What can I do to fix this and have my compressed avi files to start playing back, these files plays way smoother than mp4.
