DivFix++ is a video repair tool for AVI files. Sometimes you can't convert your AVI video files for your PSP or smartphone due to slight corruption. Because most "video conversion" software doesn't like corrupted AVI files. You can fix corruptions on your AVI file before starting the conversion. Also, you can't watch your video/movie properly on your favorite "video player" due to corruption. Sometimes downloaded videos/movies are corrupted too. You can fix them with DivFix++ if they are in AVI format. You can also preview "video download" with this tool, fix the file adds the seeking ability to the video and you can watch currently downloaded parts.
