I am trying to convert my Anime EP from AVI to Mpeg. However when I try selecting my 2nd EP [avi format] to convert, it says that it is unsupported. Both Anime EP is .avi format, has the same video and audio codec [both OpenDivx v4 and Mpeg Layer 3]. Both have same FPS, file size, everything [they both have the same exact properties except for name]. What is the issue here? Should I combine both to solve this issue?
